I checked out Mint.com, and it does seem interesting, but that is not quite what I want, I am looking for more of a program that I can use even when I am not connected to the 'net. I also do want something I can enter my petty-cash purchases into.
I found a program (for desktop linux) that i thought would be good it it were ported: 'GnuCash'

Any other ideas?
