As I'm a guy with a camera problem (yes, probably completely atypical), let me try to explain. MTP. EyeFi and microSD won't help there. I was hoping the N900 will resolve the MTP problems/lockups and allow for remote controlled cameras so I could use it for shooting stars and funky time-lapse stuff What is MTP? retrieval speed. I copy TO the HDD via USB host, but copy BACK to my main machine via eSATA. Seriously, copying Nx10G via USB (especially if it goes through a translation layer like with the NIT or a camera) is just not fun (yes, I know, the horror )
