mine dont have they problems since i oc'd to 1000, cant remember the last time i missed a call because of lag. the multitasking is awesome, good luck with androids "multitasking" :/ battery usage depends how hard you hammer it as with any phone. ine charges fine (maybe your usb is loose? admittedly that is a bit of a n900 specific issue) the browser is far superior to android imho, the "weenieness" of the apps is a personal opinion, i like the ones i have very much.
