As a big fan of menumeters for Mac (which I use to track CPU use and Network activity in my menu bar) I find I really miss it on my iPad. I just left my iPad downloading a big kindle book for half an hour over wifi and I really wish could see if the spinning icon meant there really was traffic coming through or it got stuck. I don't imagine such an app exists, and maybe if it did it would have to be via jailbreak since its kind of system level... I love being able to see network/ISP performance and install it on every Mac I use. Any thoughts?
