1. Windows 8.1 in 32bit version and it includes Office 2010whs, some questions if you don't mind my asking:
WinRT or Full Windows?
Does it include a regular USB port? If so is it USB2 or USB3?
Does it include a HDMI or Mini Display Port for showing the tablet on a HDTV?
How is gaming performance? Can you play regular 'AAA' type games on the default 'normal' settings?
How is it for online video/streaming (YouTube, Netflix, Twitch) in terms of watching flawlessly and not stuttering/buffering/crashing?
2. One USB3 port in the keyboard and 1 Mini USB on the tablet part (I guess that is USB2 - not sure).
3. I have never played a game in my life. I could not tell. The only solid number I have is the boot time which is 28sec - that is event 100 in Event Viewer (see picture below).
4. For Youtube no problem at all - and it does have an HDMI port. The other options I have not yet tried. I think the video chip is pretty good and the CPU is a quad core up to 1.8GHz. I have a Toshiba laptop with an i5. The 'felt' performance of that laptop is not really much better.
