FYI: MyBooks Professional as Quicken replacement
If you wanna migrate to Linux or mixed enviroment and looking for some serious replacement of Quicken or another personal or SMB finance management package, then check out MyBooks. Got this link to it from Slashdot disscussion about IBM offering Linux workstation business package. Site looks a little bit odd (Coming from 2001 or so), but it's not always indicate quality and/or usefulness of application. There is trial version available, so check it out.
