Just got a Hyperdrive Colorspace after reading a review on Luminous Landscape. I have been using a first generation Epson and although it wouldn't display the M8 raws it still worked to store the images but is very slow. I emailed customer support at Hyperdrive and they replied that they are currently working on full support for the M8 so I think this will be the only device to fully support the M8. Screen is small but good quality and it has a slot for every type of card and is very fast. You can buy it with no hard drive and is simple to put your own in. Worth a look www.hyperdrive.com
