what's a screen digitizer?

is it different from resistive and capacitive screens?

back to topic:

i read that nokia is going to announce a device on june 21st. people believe that it's a meego device...

am i the only weird guy here? i still receive lots of compliments that my device still looks like new after 1 1/2 years. i only put screen protectors at the front and back still the same till now...
