Completely understandable. Keep in mind that there are services running in the background keeping the device updated, sync'd, active, etc. If you are starting to see issues with the device, i.e. slowdown/lag, unresponsiveness, etc., then take a look at what could be causing those issues.
Other than freezing a few times (though google suggests that it was/is a problem with that speciific app, not my phone) it hasnt been terrible. ive had to hold down the power button to turn it off and reboot, it a few times. I just instintively did that from owning a computer for so many years, it was nearly subconcious, but it worked!
the overall motion, like going through the phones menus, or home screens, etc is still very smooth.
other than the odd random freezing (normally when trying to boot that app i mention. it hasnt just randomly frozen when "at rest"... at least not yet), im just trying to keep it that way.
So, is it normal that i cant see all of the ram actually available? I have sync disabled/manual for all my accounts (facebook, gmail, etc). and data is turned off. so aside from it monitoring for text messages and calls, im not too sure what the ram is busy doing! lol
