I was previously running Quicken 2000 and loved it. I "upgraded" to 2002 hoping to get up-to-date tax information for tax planning and faster recognition of categories based on 2002's ability to recognize businesses. My recommendation to anyone with 2000 or 2001 is to keep what you've got.
Here are my complaints. First, in order to install 2002 in the default directory, I had to uninstall 2000. The 2000 version was pre-installed on my computer, so there is no practical way to recover it. You can change the install directory, but I suspect that this will result in numerous conflicts and files not found.
The program crashes constantly, although the number of crashes seems to decrease with use.
You get bombarded with alerts and suggestions for scheduled transactions that must be cleared out one at a time (automated alerts is one of the features advertised in this version). Buy a book from Amazon.com, and the purchase will appear as an alert for the next month. I continue to get warnings that several accounts are past due, even though they are all up to date and have entries in the register. Several areas show some type of warning icon that I cannot get rid of. For example, I have chosen not to supply some information on my bank accounts to Quicken. The result is warning icons on the overview pages for the account.
Planning, tax, and investment calculations appear inaccurate. I am also unimpressed by the Quicken's inability to handle more that one Flexible Spending Account.
Finally, as other users have noted, you get bombarded with links for other Quicken services. The bottom of each page provides icons for these services, and I have not yet found a way to turn them off.
