Until last month I would agree (the future of Maemo looked very bleak to me, confined to the limitations of the smartphone form factor), but MeeGo changes things. Wouldn't it be great to see a device-neutral "marketplace" where you can get the apps (both commercial and community) you want for your MeeGo-running computer, tablet/MID, smartphone, car, TV and/or whatever else joins the party, all in one place? In such an environment I don't think the smartphone section would be the largest "consumer" of software.

I wish I had any good ones :-( The best I can come up with is for a a foundation-style entity to be formed and set up its own payment/donation system (possibly with some trusted third-party handling the card processing). I realise it'll probably never happen though.
