Please Nokia,
Make something totally open, FOSS and all, also open drivers and hardware,
With a HWKB,
And also a pen doing all what nikos523 said,
An removable battery,
An FM rx and tx,
A good camera with different focals (but don't be obscene, only one captor)
And accelelerometer, thermometer, moisturemeter, compass, gps, pressuremeter, air-quality-meter, geigermeter
Removable media
Please

I still use TX almost everyday (with a small hack to extend tx quality though)
I use fingernail all the time and stylus to edit lines and columns in gnumeric (double clicking on the same place with fingernails is too hard after the second cup of coffee).
