Re: I Wish I Could
I got my other half off Microsoft Money after more than a decade using it by mentioning HomeBank (freely downloadable from homebank.org). Runs on Windows as well as on Linux, incidentally. Very much still developed and not proprietary, though, which is good.
For Lightroom, someone's already mentioned DarkTable, but RawTherapee is also good (and again runs on Windows as well as Linux). Digikam is also very good for image cataloguing, metadata management and so on. Digikam also has raw capability built in, so might be a suitable one-stop shop replacement for Lightroom all on its own.
