This is a cure without a disease.

I don't see what value a 15" screen adds to the screen that comes with the T2. The screen on the T2 is plenty big and very readable. The only problem, as others have mentioned as well, is that you can save settings/registers/etc with long names but most of the names get cut short. They need smaller fonts or multi-lines or another interface to allow the longer names.
