Well, I think you're right.
I think my system is pretty fast, and I guess I pushed it to the hardware limits.
I just keep thinking about an N900 with 1GB REAL RAM...
I remember my HTC Universal, that comes to the market with 64 MB, but with an empty BGA memory slot, so I upgraded it to 128 MB.. that was the dream.

I learned to balancing my usage of the N900, so I rarely running out of RAM, but without its limits I would like to use it without the urge of closing programs like cutetube, musikloud, my favourite topics, web sites, music player, etc

When N900 was released, everybody told that she is a fully multitasking beast, and that is partially true, but with serious limits...
I don't know whose idea was that this device has to live with 256 MB ram...
