I've heard of android running LXDE as well. Seriously - I had a sony erricson phone once and I hated it. But symbian is globally the #1 most popular phone OS, so it has good support. I still use my N95 running symbian. The REAL decision is not which phone - its which OS. Symbian is established, but closed-source. Android is more open and is the 'new thing'. Maemo will die a quick death.
