There are potential issues that can happen when using apt-get over HAM in Maemo, due to the differences between Maemo and Debian packaging and repositories. FAM is a GUI for apt after all. There have also been reported issues from auto-removing after every use.

FWIW this is not the reason for me avoiding it, I feel this is important to point out, hence continuing this OT.
Firstly, if I wanted to use apt, I see no reason not to open a terminal and type away I don't see a need of a GUI for it.
FAM uses it's own catalogues which IMO is adding more unnecessary bloat to Maemo.
Finally the source code for HAM has always been available, I see no logical reason why this wasn't checked out and worked on first before deciding to write a GUI for apt.

Thankfully this has recently come to the attention of fmg, who has and will continue if possible to fix and speed up HAM as part of CSSU.

Tagged as speedyHAM these HAM fixes are currently available from the development repo and make HAM lightening fast. Well, as lightening fast as a package manager can be that's looking through repos full of uuencoded icons
