In my opinion its ready to depend on, but you should
be aware of 2 main problems:
- you cannot use your 1.21b-Backup in 1.22 (you have to sync all
your data with your PC, and after flashing to 1.22 resync that
data with your Zaurus)
- if you´re depending on using wireless connection, like BT or WLan,
you might have problems with getting them started/connected
But i had no problems with charging, wether with the E-BL06 or
E-BL08K (the first is the smaller, the other is the higher capacity
battery).
Sorry for my bad english, and gn8 from germany.
