Get off you high horse, Why in the hell would i be ringing MS or asking questions here if I had or intend on getting a pirated version? My opening line "Thinking of getting Vista Premium oem" simply and exactly means just that and i came on here to enquire about the possibilities of getting it reactivated (legally by MS) when i change my motherboard. I was under the impression from various posts I read that it might be possible and legal or at least a grey area hence the "couldn't i just ring up and say the board died and needed replacing?" line
I nether said i wanted or intended to run a pirate version, So why accuse me of it? I'm honestly amazed at a couple of replies here, Maybe it's just me but i find more than a few people here elitist and retentive.
Rant over
Thanks to steve, Fire Wizard and Burnsy for answering my questions, It does indeed look like i will need the retail version, I wouldn't like to spend the next 6 months worrying if I'll be able to get MS to reactivate my version again,
Still sticks in my gut though that i can only get an oem Vista Premium for around the same price as a retail version of OSX and what makes it worse i'll need 4 copies (that's retail copies!) eventually
