i don't know if i'm abusing it too much or not but i have:

3 accounts online. i had fb, msn pecan, skype (tried reducing to 1: just fb but no change)
not more than 5 browsers
tweedsuit
conky
sms one person

running widgets:
personal dataplan monitor
personal ip
conversations
media player(not playing anything)

i've done the scripts (installed property) and reinstalled the latest one numerous times with the vfs cache set to 10 as well.

and it has shown many signs of hildon-home crashing... too many times... looks like it didn't work smoothly like some have claimed.only when running NOTHING but this one browser is the phone showing proper/acceptable responsiveness.. at the most maybe 2 active windows and that's it. if go online with my IM accounts or open more browsers.... kuku
