The November issue of the Journal of Accountancy had a great article on the pros and cons of upgrading to Windows 7 if using Vista or XP.
Unfortunately my 'youngest' laptop operating system is Vista which has been a continuing problem. I've read in other magazines that if you've gotten used to using Vista and are anticipating getting a new laptop in the next 12 months, it might be a better move to wait and apply the upgrade $$$ to the new laptop purchase. Last time I checked the upgrade was about $200 for the professional version, which in today's marketplace is a pretty good downpayment on a basic laptop.
FYI - Microsoft is sending a free upgrade to many purchasers of newer laptops. My son purchased his laptop about 6 months ago and just received his free update.
If you're anticipating an upgrade to Windows 7, first download and run the Windows 7 Upgrade advisor to see if your current hardware/software is compatible.
The current article is not available online. There is a September 2009 article about Windows 7 available that you may find of interest.
