as i am writting this reply, the keyboard is out. 2 widgets are running, 2.5G connected, 2 apps and web pages are open.

currently in idle, my cpu usage is 2% and 170mb of ram usage.

as i take action (like switching between apps and web windows) the cpu usage goes up to 21% and 175mb ram.

i have no more than 5 apps installed from devel and testing.

i am also running skype, msn, yahoo and facebook im's.

when i receive an email or im, the cpu goes up by 32%, ram is up to 175mb.

almost all of my devices used half of their ram even in idle mode.
just wanna ask if that is normal.

if i run my device at this rate continuosly, mt battery will last for 18-20 hrs.
