I've been using Windows8 for the last week, and I LOVE IT! It cost me £25.00 as an upgrade from '7' (from Microsoft) I decided that at that price it was worth sticking on my (hardly used) laptop, just to mess around with...after all the bad press I'd heard, I really didn't think I would like it but I have to say I've been very pleasantly surprised. 20 minutes messing with it and it's almost 2nd nature...very logical I think, and very 'slick' also really fast. I'm upgrading my work PC to W8 in a week or two...I'm just going to check on the Pixologic site for any compatabillity issues with ZBrush (from what I hear most people have had no issues with Poser Pro 2012, so were good there!) and a further check with e-on RE Vue10, and we're good to go, no worries!
