PROS:
-Specs - price for performance - This is a sub $300 tablet that has an included keyboard, 4gb of ram and 64GB of storage. Hard to beat those specs for that price. Sure, the screen is only 1280x800 pixels, and its an Atom processor (though it is the newer Cherry Trail version), but this little machine works really well for day to day tasks. Those cheaper machines with only 2GB of RAM, 32GB of storage and a previous generation Bay Trail processor pale in comparison. Spend about $100 more to get this machine compared to those others and you will get better performance, and still save $300 compared a similarly specced Microsoft Surface 3 (not the Pro; the Surface 3 base model also has a Cherry Trail processor, only 2gb of ram, and 64GB of storage) plus its $120 keyboard (which is not included in the Surface 3 base price) and you'll be really happy. Note that you'd have about 35gb of usable storage space when you first turn the laptop on.
-Form Factor - This little machine can fit (awkwardly) in my winter coat pocket. I'm pretty sure there are some cargo pockets this would fit into. Not that you would ever transport it that way, but the point is this thing is really compact. It's a bit heavy, but that is really related to ensuring proper balance on your lap or on a table when you have the keyboard attached, so the weight it forgivable. Some people will complain about the weight, but I don't see it as an issue. The tablet secures easily to the keyboard with magnets (no button to push or anything). The connection is secure enough that you can lift it by the tablet portion and the keyboard remains securely attached. Minimal effort is needed to separate the two parts. Also, unlike a Surface 3, the Asus T100 can easily be used as a laptop. The Surface 3, which does not have a hinge connecting the tablet and keyboard portion, does not do that as well. Not an issue if you are using them on tables, but definitely a consideration for couch surfing and working on the train.
-Straight Performance - The Asus T100HA is a workhorse for its size - remember this is essentially a tablet with a keyboard and not a true laptop. Internet Explorer, Chrome and other regular Windows applications open quickly and run well. Since it has 4GB RAM I can run lots of programs at one time without an issue. I even installed a recent 3D game (Divinity: Original Sin) just to see if it would run and found that the game was smooth enough to play on this *sub $300 tablet with keyboard.* Blows my mind really.

Middle of the Road - items that are neither good nor bad, but should be noted
-Keyboard - There's not a lot Asus can do with the keyboard to make it really great at this size and price. I've used a netbook before (a really sturdy Acer Aspire One that served me well) so I knew what to expect. Its serviceable, but feels a little bit flimsy and hollow. Typing on it is just fine for me. I'm typing on it right now actually with minimal errors or issues. I wouldn't want to write a thesis on this, but emails, short documents, etc., will work just fine.If this is a concern, I'd go out to a store and check it out since it is definitely a preference thing. But again, if you come into this purchase with the right mindset (this is a sub $300 tablet with included keyboard) you really shouldn't be disappointed.
-Camera - its just okay. Nothing amazing, and definitely not something to rely on to take important photos. I don't know why they even put a camera on this machine except to list it as a feature. Just about any phone is going to have a better camera, so just use that.
-Speakers - they produce sound, but not sound you want to rely on for much. Again though, what would you really expect at $300? They work for Youtube videos and minor stuff, but I wouldn't rely on them to play music at a party.
-Wifi speed - The wifi is not slow by any means, but I will note that it is not capable of maxing out my 50mbs (essentially 7MBs) internet even on the 5ghz channel.Instead of 6.9MBs on downloads, I seemed to top out at 4.5 to 4.9MBs. Not a deal breaker by any means, but something to note. But really, with only 64GB of storage, you can't be downloading too many large files anyway, so something to note, but not a negative.
-Screen - serviceable, but unremarkable. Some backlight bleed, generally low contrast ratios, and low resolution will be complaints some people have. Not an issue in my use since I'm not buying this machine because of the pretty screen. I'm buying it because it a super portable machine with enough power to do what I need it to do.

Cons: Some wonkiness
-Onscreen keyboard - Occasionally the tablet won't pull up and onscreen keyboard which leads to an inability to do any typing unless I either restarted the tablet or attached the keyboard. Annoying, but hopefully something that can be fixed with a software update. When the onscreen keyboard does pop up, it works just as you would expect it to and just like any other tablet.
-Portrait Mode - This is maybe a bit nitpicky, but the tablet doesn't really know what to do when you are looking at the desktop in portrait mode. Rather than put black bars at the top and bottom to keep the proportions right for your desktop image, by default it stretches and distorts the image to fit the screen. I'll have to search in options to see if that can be easily fixed (guessing it can), but stretching shouldn't be the default setting.
-Switching between landscape and portrait is not always the smoothest transition, and it has gotten stuck a few times. Not a deal breaker, but definitely something that should be noted. Most times the tablet figured the problem out, one time it completely failed and I had to restart it.

Overall, I took off one star for some scattered wonkiness, but this is really a solid value at sub $300. Use it for the things it is good at - couch web surfing, portable productivity, extremely light gaming - and I don't think the T100HA will disappoint you for the price. If you need a more refined experience, definitely check out the Surface 3. If you really need a pretty reliable, portable, web surfer and word processor on the cheap, I really think the T100HA is hard to beat.

Please drop any questions you have into the comments and I'll try to answer them!

Out of the box, there's really nothing else at near this price w/ so much storage, a current gen processor and a reasonable amount of RAM to run Windows 10 on. Great! It feels solid too. I like the brushed aluminum, especially. I do wish the the keyboard part could be plugged into power instead of the tablet part and you could use it as a docking station rather than having to unplug from both the keyboard and the wall when switching over to tablet mode. I also kind of wish there were a few more USB ports (USB 3.0 would be nice)--maybe a USB on the tablet part--and it seems like you could add some extra batteries to the keyboard part. All of these things cost money though so it's understandable they've been left off.

As far as performance, this holds up pretty well. You can do your basic netbook-y type things like email and web-browsing no problem at all. I have occasional issues with WiFi dropping out and I have to put it in and out of airplane mode to get it working. You can easily watch videos and movies on it and the screen looks really nice, though a bit shiny and prone to getting all smudgy w/ finger prints. Programs are a little sluggish getting started (to the point where it's really hard not to keep clicking and opening five browser windows) but once they are going, everything runs well. I have no problems getting things recognized via USB but the Bluetooth I have the same issue w/ as I do the WiFi where I have to turn it on and off occasionally to keep it running. You can even do some limited gaming on it, esp. if you are into older or indie titles. I got Rocket League to work as well as Grim Dawn, granted they were both on the lowest possible settings across the board.

In my first couple days of owning it, I was very impressed. Since there's not that great of app support in the Windows store, it was kind of annoying to have to run desktop versions of some applications in tablet mode but that was my only major complaint aside from the issues above, which were as much of a hassle as anything. However, at some point--I believe after an automatically installed Windows update--the sensors in it stopped working. This means auto-dimming doesn't work but worse than that, it now now longer auto-rotates the screen in tablet mode. (It also displays the log on screen sideways when you first boot it up in laptop mode.) At first this seemed to be more just another annoyance and maybe it is but it severely limits usability as a tablet. It's no good for reading and even worse to have to type on the giant landscape mode keyboard. I feel like I'm constantly fighting with it to do anything and find myself doing things like attaching the keyboard to write a short email and then detaching it to read something in the other room. Also, w/o my involvement, it decided to redo all the power settings to not allow programs to keep it from going into sleep mode when I am listening to music on it, I have to either dig into settings to disable power saving or wiggle the mouse every five minutes to keep it from stopping. All and all, while no one thing about this completely ruins the experience for me, the fact that it's not perfect to begin w/ combined w/ other issues cropping up so soon after purchase, I really cannot recommend this product to anyone.

I contacted ASUS chat support about the above problems and they gave me a package to drivers to re-install which didn't help (and I told them I'd already tried) and contacting their support via email a few days ago has yielded no response. I would love to get the issues solved as I think this would be easily be a four star product if it worked correctly.
