I'm a linux guy, lately sort of edging away from Ubuntu towards Mandrake, dunno why. As long as it's not stupid Red Hat it's good linux.
But I can't lie, I use Windows a helluva lot more often than I'd like to admit. Primarily Win7, although I still have XP-SP2 and 98SE on older machinery.
Spent big bucks on Win7 Ultimates (32 and 64). And now Win8 has been around long enough to overcome the worst driver/API teething issues, get a service pack, mature a bit, etc.
Is it worth the upgrade? Yeah, I've done my research, all the MS-affiliate nerds and gutless review sites are proclaiming Win8 is all that, harder, better, faster, stronger. I believe it's true, just suspicious of the hype. So I appeal to TBCS gang, men with balls and powertools and reckless disregard for any technical fluff which isn't written on the hard specs and datasheets.
One thing I see on Win8 which I instantly reject is new interface. Looks like crud, I'm old fashioned and want a PC that does stuff far more important than stupid social networking gossip and constant vicarious updates about every trivial little change in posture.
