@sapporobaby:
Searching around Maemo may definitely be a bit cumbersome for "mainstream" users, but I can't see where the problem with the built-in installer is? The package manager has a few simple options, where one will update what's installed and another will list all packages available that could be installed. Not that big a list either, unless you have added a lot of repositories manually. In fact I think this is the simplest by far installer I've seen on any portable device -- it's usually much more work to get something installed on your general PDA or smartphone.
