If you don't have a way to copy microSD cards using your computer, pop out the 32gb that comes with the TB and pop in the microSD card from your current Droid. If you do, copy your data from your current SD card onto your computer, switch to the SD card from the TB, and copy everything there.
Most current apps have been built during the days of 512mb internal memory devices, and they save their data on the SD card or they get rated down and/or uninstalled.
Regarding the OP, I'm going to use everything I use now, the device really doesn't matter. The changes I'm going to feel most are more internal storage and a front facing camera. I'll go looking for a video chat app if Skype fails us. I'll likely reinstall a few nice to have apps that I uninstalled because I ran out of room on my D1.
