Exactly wat are all these TOUCH roms available

---

I come from the wizard where customs roms were famous for speed and reliability, now i finally got a wing and im coming across all these new TOUCH roms, how do they differ from the stock besides speed and reliability?

Usually incorporating TouchFLO into the UI (swiping finger from bottom to top to "open" the interface). I don't use it much (it can be turned off, and most I've seen have it off by default).

Also Programs like "large Start Menu" installed
