Windows 2k7 is simply a huge memory hog. It has a new interface that isn’t bad, but like any change, will cause problems.
Worse of all, people who save docs in native 07 format will not be read by previous editions of Word, etc. That’s M$’s way of getting everyone to buy this new, higher-priced stuff.
Not exactly true because MS lets you download for free, an 07 compatibilty patch/fix.
