I"ve had mine for a couple of days and so far the biggest challenge is the lack of on device storage. When you first turn it on you only have 4 GBs of space out of the 16 GB on board. I didn't even try to install the free MS Office 365 on the device as it would have taken the storage down to almost nothing and nothing kills SSD/eMMC storage quicker than filling it all the way up. I haven't really found much to uninstall to free up some space (this is a MS signature device). The second biggest challenge is a familiar one for Windows Phone users - a lack of apps. I only found a one of my finance apps (Bank America, no Amex, USAA or my credit unions), no UPS or Fedex (although there were some third party solutions), was surprised to find my football teams official app was there (maybe because of the Big MS Surface NFL tie in), MLB At Bat was only there in MLB.TV form, and was just generally disappointed in the quality of the Universal apps so far. There is no touch compatible MS Office app (still waiting for the MS Office that has rolled out to both Android and iOS). The Netflix app was petty poor quality as all my other devices get HD video quite easily and this had pixelated video that never settled down (I have 20Mbps down, 10 up). The built in WiFi seems somewhat weak in its 802.11n mode compared to my other laptops and tablets (3 Android, 1 W8, 2 W7). Didn't really care for the in hand feel due the hard plastic back. Other than that the performance is fine - especially when you consider it only has 1 GB of RAM and the CPU is a 1.33 GHz Quad Core Atom (bursts to 1.86, I believe). The IPS display seems pretty nice (especially considering the price - $99). I added a 64 GB micro SD ($24.99 storage @ NewEgg) (must factor this into the purchase because there is no way to make this tablet usable without it) and seems to play music and video without too many problems. The Frankenstein nature of Windows 8 rears its ugly head as too often you are dropped into the desktop version of the Control Panel with hard to hit targets to set things up. I also find it difficult to figure out where certain settings were (even having used Windows 8/8.1 for the last 6 months - my laptop is non touch so I only use desktop apps on it). Not sure if I'm going to keep it or not - it's definitely a decent value @ $99 but isn't up to par against my closest competitor - an Asus M176 (7" tablet, 1280x800 IPS screen, 16 GB with 11 GB free, 64 GB micros SD works great, same quad core atom as the Toshiba and 1 GB RAM. The display is a little washed out but otherwise is much more usable than the Encore and it's regular price is $125 (have seen it as low as $110) with no taxes and free shipping. And the app situation and usability as a tablet is WAY ahead of the full Windows 8.1 Desktop/Universal app mess.
