1) 32bit or 64bit?
I know the reasons for buying 64bit, can use more RAM and system can do more calculations etc...but is 64bit supported enough yet by 3rd party devs?
To be honest 64bit would probably make little or no difference to me at this point, and I do not want to open a can of worms by installing an OS that does not have driver support...but if its reasonably well supported and 64bit is the way of the future, then I would rather buy now.
Is Premium the most suitable and cost effective version for a home user?
As far as I can see, there is no benefit to a home user like myself purchasing the Ultimate or Professional versions.
Should I go for OEM or Retail, does it really matter?
Why is there such massive variations in price?
DSE is selling Premium 64bit for $389, yet Expert Infotech is selling Premium 64bit for $192.54
5) Multiple computers?
Can I install my OS on multiple computers I own, or have to pay for additional licenses?
