I have one importatnt question, it's good idea to buy now windows 8 or better wait for more updates? Actually i have windows 7... In this time Windows 8 is better than 7 ?
Most businesses (Microsoft's bread and butter) are usually a version behind anyways; XP is still king. So the corporate clients aren't going to buy, (they haven't bought Vista/7 yet). So I can't see how they're going to push a tablet-centric interface onto the business world 7 years down the line. They simply won't.
I upgraded to windows 8 for $40, installed classic shell (regular start menu with an option to disable "hot corners", I never see the metro interface) and now I have windows 7 only better. It feels faster, looks cleaner and everything seems to be working. For that price I recommend it. There are many solutions to the wacom…
Personally, I'd just stick with 7. It's the new XP for now, I think. It's stable, works great. Haven't tried 8 yet, but everything I've seen about it makes me queasy.
