Actually, I use those functions very rare, but they are there, I know I can use them when I want. On the other hand, I don't really have to have them in the next phone.

I might not right about "other phones cannot do", but I'd like to have:
- record every phone call automatically as recaller can do.
- functions that Conky has.
- I can install dictionary MStardict
Oh and
- ssh to my lab computers, for file transfer and use programs with X-windows
