I am using Money 2003, i have been a user of Quicken for years now and just recently switched.
Money 2003 has the same base set of features as Quicken, but I find Money 2003 is VERY, VERY sluggish. I see delays when entering in transactions, and I am running a 1.2ghz cpu and 512meg ram....more than enough to run a personal finance program.
I just grabbed Quicken 2003 Home and Business Premier edition and I plan to uninstall Money and go back to Quicken, it just runs so much faster!
