I loaded the Windows 8 DP many months ago on a virtual PC, I pressed Start and instantly hated it. I even deleted it without a second look.
I went back to Windows 7...but because I work PC retail, I decided, what the hell may as well give it another bash. So I loaded up Windows 8 RP last week, for reals this time and with every intent of hating it. I hate to admit it, but it has grown on me.
It is definitely faster, cleaner and the Metro live apps are pretty sick. What Microsoft has done is very clever, they haven't made everything MSN account based, they have integrated all social platforms in to one...and it works! Without even having Outlook installed, I have a live app fetching email from both my Google and Live accounts, another one updating Facebook and yet another app which integrates MSN Messenger, Google Talk etc.
I can see Micro$oft coining it with Windows 8 when it is released - you know why? Because the computer, tablet and phone will all be running the same OS (idea stolen directly from Apple lol). Only difference is, this time everything will be compatible with everything else and the less savvy users won't have to worry about the Android phone in their pocket, the iPad in their hands and the Windows PC all running different operating systems and confusing the shit out of them. And let me tell you, most long time Windows users are reluctant to make the switch to the more expensive, less compatible and exclusive (you can only buy this R400 cable to use your Mac) club that is Apple products.
