Hi there
a bit late now but possibly of help to others buying a new computer IN STORE rather than from the Internet.
When you buy the computer haggle with the salesman to throw in at least a copy of Windows 7 Home premium - it won't cost the store much and in todays economic climate they will probably throw one in.
Often a Copy of Office is included with a new computer (Student & Teacher edition) -- so offer to swap that for Windows 7 instead .
Most stores - even surprising unexpected places like Dixon Digital in the UK will do this -- if the Salesman won't do it just ask to speak to the manager -- there's no harm or Stigma in doing this and the worst that can happen is they say no --so what have you lost.
99% of the time you'll have your computer and a nice fresh copy of Windows 7 - so when you get home make your Backup as per the instructions -- then WIPE the disk and install your nice NEW copy of Windows 7 Bloat free.
I just bought a new Netbook in Manchester UK for 249 GBP ( I can get 17.5% VAT back next weekend when I'm flying home for a few days just get the VAT chitty to HM customs at the airport) and I still got a copy of Windows 7 home premium thrown in.
(The netbook came with XP Home installed - I want Windows 7 - although a technet suscriber I always like to haggle and bargain in these types of shops -- I'm NOT from the middle east either


It just makes the chore of shopping more fun).
I find a Netbook indespensible these days and it makes flying so much easier as I've got a Professional Photographers jacket with loads of LARGE pockets so this doesn't even have to go as Hand Luggage either. I just walk straight off the plane at the other end - no luggage to pick up etc.
Cheers
