Bender C :
For a PC? I went from Win XP to Win 7 without using Vista, I don't see the reason for Win 8 unless you like the interface, the minor increase in performance or have a touch screen. If I'm going to build a PC why would I even consider if my main purpose is for gaming and Internet usage, I think sticking with Win 7 64 bit for a couple of years is better in the long run so I don't run into driver issues and the potential for troubleshooting headaches (They are built on the same platform rt?) What do you think, should I buy 7 or 8?
Or will win 8 be the new standard.
Truthful answer might be 'its a slight gamble'. You may install on a machine that experiences problems, you may not. From what I've seen in this forum the most difficult problems have been with machines running UEFI instead of BIOS. I've had no problems on any of the machines I've set up bar one which had a wireless adapter driver problem, but these were all upgrades to older machines with no UEFI to worry about. Meanwhile I would go ahead with 8, especially if you want to install on a small SSD, it takes up less space... (It's almost worth it for the Music App which gives you access to Xbox music!)
I barely use the Start screen, once you're on the Desktop there's no difference in operation, you quickly get used to using the Windows key shortcuts to everything that the Start Button gave you access to. If you're building a replacement machine it's probably not worth the added expense to upgrade, provided you have a Retail version of 7 you can transfer.
If you have to buy an OS for your new build, W8 Pro upgrade would be cheapest if you have an old copy of XP kicking around...
Of course there are many features in 8 that are unavailable in 7, there are plenty of 'comparison' sites to highlight them, ultimately it's down to you, though you can still get the Evaluation version from here
