M1000 backpack - some advice?

[Guest drwilt]

Hi, I've just ordered an M1000 from Orange to replace my iPAQ 3870 - I'm thinking of getting a backpack so I can use my existing CF cards I currently use via an adaptor jacket with the iPAQ.

Am I right in thinking that an XDA2 backpack is fully compatible with the m1000?

Is the camera obscured when the backpack is fitted?

How do people rate the backpack's performance?

Thanks in advance for your help!
