-Over clocking all 4 cores to 2ghz a piece, if possible. For some serious horse power to compete with newer tablets coming down the road. Of course needs to be stable or doesn't overheat n melt the device..lol
-some sort of uploader for native browser or even compatible with 3rd party browser. For ex. Safari on my iPad couldn't upload or download on stock setup. With jailbreak n Cydia, I have safari downloader, which enables download manager in native browser, and safari uploader. Which allows me to upload something thru the browser by accessing device files. Ex. I go to a site I need to upload resume. I just click on upload link on page, then it accesses my files. Then I search for resume, click on it , and proceed to upload.
-Some sort of futuristic theming around Transformer prime, movie or whatever. Completely changes the look up to a more high tech device.
-optimize and increase camera/video quality even more, if possible. I know it's already good, but could be a way to raise MP rating through software adjustments.
-an app like g power, available from Cydia for JB iPad. I double tap the top of screen(through activator) and it brings up quick menu to power down, reboot, or respring(if that applies to android). Or maybe just subtle gestures to access important features of device or apps.
-make skype and any other video chat apps that don't work with prime, work
-Tegra 3 supports 3d. Maybe make a way to enable 3D mode, with or without 3d glasses.
-see if any ways to optimize/beef up the gpu even more.
-maybe a way to download and install IOS tablet apps/games through an emulator or some other way. So we have access to even more apps, especially since IOS tablet only apps far outnumber androids.
-dual boot capabilities , possibly windows
-hack pad tool set..lmao
-a special feature, cybertron mode, that whenever Prime is in vicinity of an IOS device, we can disable and shut it down. Then we go over n show off how cool the prime is and enable that device to run run again. Showing that we can amd did, fix the device wirelessly

or if you want it completely disabled for life, so be it.
Just throwing stuff out there, I'll update this post as I come up with more ideas.
