[Windows 8 General] _gl:
Got mine yesterday. First impressions - overall pretty good. IPS screen is nice and sharp, black levels are decent. Not quite as saturated (colourful) and super-black as the best, but not bad. Wifi reception is good, using my iPhone with 3G as the gateway via Wifi it has no problems getting a good signal one floor up (my old Gadmei E8-3D tablet would loose the signal about 5m away already). Battery seems decent, but need more time with it (and it may improve a little after a few full charges).

CPU speed isn't bad for a tablet, I'm not sure I'd want to use the slower Baytrails though (eg. W3F) so I'm glad I paid for the 2.4GHz boost. It does seem to throttle it down though if all 4 cores are maxxed. This is most likely thermal management, when total core utilisation < 75% or so (TBC) if does get up to ~2.33 GHz (it doesn't seem to be a true 2.4, if so then kinda sneaky rounding up like that), but then it drops down as a cores get v. busy. On the plus side, tablet only gets warm, never hot, even when running 3D Mark (though I didn't try running a 3D app over a long time yet). Thermal management seems good. There might be scope to push it a little via the BIOS temp. settings, but I'm not messing with those for now.

Tablet feels nice in hand and considering the size isn't too heavy or thick imo. But it has a small ridge all around the edge - this protects the buttons and ports a little by recessing them, but also slightly digs into your hands slightly. Not loving that, it's not painful but slightly uncomfortable. They should change that on the next model.

Keyboard is pretty good actually, thin but fairly rigid, as is the touch pad and button response. Feels decent quality, surprising how much travel there is in the buttons/keys considering how thin it is. Touchpad mouse tracking is good for general use, though if you try to do pixel-accurate scrolling it does sometimes jitter a bit. But you don't notice it for normal use. For more accurate mousing it's definitely handy, the touch screen will struggle for fine control sometimes, especially with apps that aren't DPI scaling aware. The magnet that holds the tab to the keyboard is very strong, no danger of it falling off (even upside down I think). But the soft and thin cover provides zero protection from dropping, so I'll look into getting a better case when it goes out the door.

I'm still setting it up - have calibrated the screen (max brightness is around 220mcd, contrast ratio around 930:1, good for an IPS screen). USB 3.0 seems to work though I still need to test the max bandwidth. It also does not work with my Seagate portable USB 3 HD - it briefly detects it, then disconnects it. Suspect it cannot supply enough power, so a powered USB hub may be necessary (will try that later, I can measure the USB current too).

Office trial is there, haven't activated mine as I don't intend to pay for it, so won't use it anyway (lots of free alternatives available, eg. OpenOffice). You have to activate it before August 2015 though or it expires. OneDrive app is there, but I haven't looked at it yet (probably won't use it either).

3G Huawai stick is there, but seems to take a full-size SIM cards and I only have a microSim, so will buy an adapter. There's a mobile-something app that seems to do text messaging, maybe even phone calls?

Anyway, so far overall seems a pretty good package, I'd recommend getting the keyboard unless you definitely won't need it. It's a well thought-out solution and pretty compact, and no wires to worry about or wireless batteries to run out.
