hmmm, quite a very extensive list...
However, I think I will finally get the GBM. I'm going to try it live so that I make sure I like it. At least, I can carry with me in a very small form factor tons of GBA, GB, NES, MS and SNES games. It also has some kind of "collection" value, in a few years, I would be able to (re)play all those games in a very attractive platform. I only miss CPS emulation (and similar), but well, I always have my laptop + pad combination.
Thanks to everybody for the comments, a really nice forum. I will probably drop in once in a while.
