Rivetess' computer - and indeed mine - need W7, but would putting the W8 Beta on a fairly powerful laptop be worth it? The W7 RC ran well for some months, and I was offered a great deal on upgrading to a licensed copy at the end.
With a month to go, they ran out.
But are such offers common? I'd love to get rid of Vista on both laptops, but again, having an OS that's tailored for hand-held devices might be a PITA. Is it too early to tell?
