I found that running Windows in VirtualBox lets me run all 4 Windows
programs that I rely on (of which Quicken Deluxe 2011 is one). Since it
seems to run seamlessly inside Ubuntu, I like this as my solution. Now
Windows 7 will probably only be used for games :-) .

If I could find real good equivalents among Linux applications, then I
wouldn't even be using these, but it seems that Intuit is adverse to
porting their best-selling applications to *ix, so until they do, or a
real equivalent comes along, I still need Windows (regrettably).
