I got everything to one page of Go Launcher Ex. (Obviously got rid of all the ad and spam widgets the Go Launcher puts on by default.) Turned off background services and sync, and only use wireless to transfer mp3's from this point.
I'm still not sure how I feel about some of the replies to me specifically... I don't appreciate and don't deserve the device, because 1) I try to use wireless and have problems and should know not to use wireless, and 2) I don't root and gut the device so it runs nothing but the onboard music player, and 3) I followed advice in the FAQ, but should have realized the parts of the FAQ are dated and should have known to ignore those parts. So I should just sell the iBasso and use an ipod / Android phone / whatever.
Gee whiz!
