The TP2 has many upgrades over the Vogue but you do sacrifice a few things too. TP2 has the g-sensor, bigger screen, more ram, hardware keyboard, and many other things but it doesn't have a d-pad, it is a lot bulkier and heavier, and the battery life is not nearly as good. You'll have to decide what features you want. The TP2 overall would be the more advanced device.
