FWIW, I work for a software company, and we have (anonymized) statistics from our users. Nearly 60% have Windows 7 64-bit; we test the most in this OS. (The next closest are 7 32-bit and XP 32-bit.)
I’m another ‘serial late adopter’ and after previous experiences in changing versions of Windows, I expected to hate it.
I was wrong. It’s great. I’ve had very few problems.
I was going to take my old PC home and use it there, but I’m rethinking that because I don’t like XP anymore. (This from someone that ran XP in Classic 2000 mode for many years after they finally made me switch over. :p)
I do have Pro edition because I required the XP VM for some of my older apps that I can’t get rid of.
Side advice: I was also avoiding the Office upgrade vigorously, after the 95 debacle. Skip Office 2007, go straight to 2010. It’s typical MS - push the software then actually fix the second version.
Only one problem: my excellent Basic interpreter (UBasic) which is old and 16 bit, will not run. Yes, there are other free Basics out there, but none has high precision (1000 digit) arithmetic or built in number theoretic functions. Everything else works fine. Including my old editor that hasn’t been seriously maintained since 1995, but it runs without a hitch.
I have a scanner from 1995 that I couldn’t get to run on 64-bit Win7 (it worked as a plug-n-plug on my old XP box). That’s been my only “issue” in the past year and a half.
