I agree with you!!:rolling: the case is limited. Last year i used a soft leather case sold buy Nokia for a phone and charger,they were being sold sale for just 1$ !!!!!
I carried that in my bag but it has got a belt loop. It holds the X30 exactly!And has room for a second battery though its a not like a case!!
For a few weeks ive been useing the dell case with redused elastic!! the way it came it was far to tight a fit, Now i use that with the 950ma battery then when useing it i change to the bigger battery.Its not ideal.
If you use a battery pack then you can use the origanal battery and any case for that then just plug in before you use your X30

Im looking for a solution too!!:)
