@Dan 10 re: Acer

Can't comment on your personal experience but got my Acer upgrade within a couple of weeks of payment.

Acer's process seems much better than others, you pre-ordered (in my case in September), payment only requested when W7 available and shipped shortly afterwards. Good communication along the way too - can't fault them.

I have a friend who needs to supply proof of purchase for a Samsung which was an insurance replacement (so no reciept) has to register then order after Jan 1st or somesuch.

Acer just asked for date of purchase (as well as serial #) - all very trusting and I have little intention of installing it either - at least until SP1.

Vista aint as bad as advertised anyway(!)
