Is 50g good or crap?

[Alvaro]

here the main reasons why I prefer the 50g instead of Prime:

- Prime has a Li-Ion battery, so I am not so indepent as with AAA batteries. That was the reason why I did not buy a Prime.
- Prime has not a SD card slot
- Some people says the colors of the "2nd" or "3rd" keys are difficult to read.
