Reasons I intend to buy a Pro:
I have a lengthy train journey to work. On the way in normally I write, on the way home I watch video.
I use Office heavily (I know I'll have to buy and install on the Pro but thanks to work I can get Office for about USD10). But I write scripts in Celtx so would like to be able to install that. So full Windows 8 allows me to do that.
My preferred video watching program is KMPlayer so I can also install that. Sometimes I like to watch an old DVD and I have a light, robust DVD player and thanks to the USB port I can watch that.
I also fancy installing some old full PC games (not sure which yet) and it's great to have the flexibility of the full Windows back catalogue (not just Angry Birds etc, although they are fun too).
And in all honesty the widescreen dimensions are my favourite viewing format - I can't really understand all the negativity about that. For films - perfect. For everything else, perfectly fine.
Battery life could be a tad better, but I'll have a spare recharger at work and Power Gorilla are working on an adaptor for the Surface so if I need emergency longer battery life I have that option.
Just about everything on the Pro seems to suit me perfectly, except... when are they going to release the damn thing!
It's getting frustrating now. If they leave it any longer they are in serious danger of losing the excitement to any other company that can deliver something similar sooner.
