One issue which has reared its ugly head on most current tablet OSes is how to deal with legacy apps. For the upcoming HP TouchPad and the shiny, new webOS 3, the challenge is how to handle apps created using the older Palm Mojo SDK. As the Touchpad nears launch readiness, however, HP has finally revealed its response in the latest beta build of its tablet emulator.
Right now, Mojo apps default to running in their original resolution — a Pre-friendly 320×480. As you can see, the emulator also defaults to rendering a virtual handset around the app. HP has included a way for developers to tag their apps so as to utilize the TouchPad’s full 9.7″ display, though doing so causes the virtual gesture area to disappear. That’s not a problem if an app offers other built-in navigation options, but it could certainly cause issues in some cases.
Of course, the emulator is still in its beta form and HP has released four versions between April 12th and now. As they continue to update, the rough edges will no doubt be smoothed out.
