Where's my auto update API? You'd think a feature so basic, so simple, would have been integrated into commercial operating systems long ago. Instead, we have this ugly mish-mash of auto update applications, each taking up memory in the background, because commercial OS developers haven't figured out that making things easy to update make people happier in the long run. Windows Update should update everything on my system, regardless of if it was produced by microsoft, or by adobe, or by google. Apple Software update should do the same; it would just make life easier.
For me it's just Skype and Opera I haven't installed via apt. I'm told there's a repo for Opera, though.
If the people at Bibble Labs wanted to provide a repository of their own for Debian/Ubuntu (like Wine does) instead of just downloads of the program, it would work for that as well.
