It’s happening.

The two biggest disabling issues making it impossible for serious photographers to use the iPad as a portable photo processing device are the paucity of good photo processing apps and the iPad’s low storage capacity.

The former issue is being rapidly resolved as new processing apps geared to touch screens seem to be appearing wekly.

The latter has finally been addressed by some clever people at Hitachi.

The device, priced at $200 and available in 4 weeks, will behave as a wireless hard drive for your iPad. So, if it works as advertised, that means that you should be able to download your RAW files to the device and then process the images from your iPad. Whether direct download from a USB card reader to the G-Connect is possible is unclear, but if it is and if delivers as promised, I’ll be in line.

Given that the primary (only?) reason to buy a 64gB iPad over the 16gB one, a poky 48gB storage increase, is if you want to store lots of videos or RAW files on your iPad, why not get this device instead? The price increase is the same, the weight penalty minor – it’s likely little larger than a notebook HDD – and you can use it as a wireless disk with any computer.
