I cant speak for everyone, but my experience with symbian on the N80 and in particular, this N80ie firmware, closing apps do not fix the issue. First off, this new fw starts out with about 2mb less available ram from the start. Secondly, symbian seems to have the same issues windows does.. It does not properly reallocate your memory when you shut stuff off.. Yes, you get some back, but not all.. Some of it leaks into symbian never never land and before you know it, after using agile, web browser, the music player, and symella, you close em all and you got 6 mb left.. Time 4 a reboot.
