I agree with a lot of what you say, and even echoed your same thoughts in
my thread. Especially about the need to contort the device in ways it wasn't necessarily intended for, to play Steam games and the like. The capability is awesome for those who want to do it and have the patience to plug in peripherals or configure GestureWorks, but if gaming is what's most important to you on a tablet, the iPad is obviously the way to go. I think Windows 8.1 tablets easily beat Android tablets in gaming though.
Parts of your post fall apart though. For example, I'm not sure what tablets you're referring to when discussing size and weight. All of the Windows 8.1 8" tablets come
extremely close to the iPad Mini in dimensions and weight. It's like a .1lb difference, and that's mostly just because they're 16:9/16:10 instead of 4:3, so they're a tiny bit taller (yet still perfectly comfortable to hold long-term with one hand).
Not a "behemoth" at all, I really don't know which tablets you're directly comparing here. Are you sure you're not comparing the Nexus 7 to a 10.6" Surface? Other than the iPad Air, 10/11" Windows 8.1 tablets running either ARM or Bay Trail are almost the exact same size and weight of most Android tablets and the iPad 4.
Battery life is also not an issue like you claim. Yes, Desktop apps can run unhindered, but only when the device is actually actively being used. All Desktop apps are immediately suspended when you turn off the screen and the device goes into Connected Standby - only metro apps that utilize background tasks like phones/iPads/etc. do are allowed to run. The Dell Venue 8 Pro gets 7-10 days of standby life while still continuing to get email, IMs, Skype calls, etc. without issue. I know that's not nearly as good as an iPad, but it's a far cry from what you're describing too.
So while I completely agree with some of your sentiment, most of your post seems to be clouded by complete misunderstandings of the actual products available to buy now, how they compare to the competition, and especially when it comes to sizes and weight.
