A better thing to do would be to go out, make it, and get it on as many Android and jailbroken Apple devices as possible. Make it a 'must have' jailbreak app. It worked for notifications. If it's something that makes Android tablets easier to type on than the iPad that'll get their attention too.
The magnifying glass is used to set the exact cursor position, and can be invaluable when trying to position the cursor between similar looking letters on a mobile device.
There's lots of web pages where it's impossible to select text (sometimes turning off JS helps) on the iPad but the phone does it fine.
In some HTML text boxes it's just impossible to edit anything.
Selecting characters within a word is painful, it's far easier on the phone as it has an optical cursor - later Android phones have dropped this so I wonder if they're painful too.
I would like to try it myself on a device first.
I hope the developer is willing to either: a.) open source his demo so other devs can try it b.) publish the demo in the App Store (or Cydia if Apple says no)
