I had to replace my n900 about 6 months ago when my charging port started getting flaky. I ended up getting the HTC Amaze. Dual-core, 1 G ram, 16 G storage. I've got a 32Gb microSD card in my Amaze, bringing storage up to 48Gb. Small enough to put in your pocket. Just got the ICS update in the last week. The HTC one series is slightly better in some ways, but no removable battery or microSD slot. I get around a day of battery life. Android's multi-tasking isn't anything compared to maemo. I haven't tried any real multi-tasking since the ICS update, which is supposed to use the dual-core much better. Just my 2 cents worth.
