Bought this and the GENUINE BLACKBERRY 9800 TORCH LEATHER BLACK POCKET CASE at the same time as I wasn't sure which would be most suitable. I would be happy with either product. I find I am using this luxury Black leather case the most a) I like the flip up cover that doesn't create rub on the screen, b) your phone is still in a protecting cover whilst using it so at least has some protection/shock absorption if you drop it on it's back or side c) it is held securely in place by a plastic frame within the cover d) easy to access all functions even with phone slider extended
The GENUINE BLACKBERRY 9800 has the battery saving feature but as the case is quite a close fit, albeit it with a soft felt interior, I felt (rightly or wrongly) that continually removing and replacing the phone could create some rub on the screen. This concern could be easily remedied by use an LCD protector
