Can anybody recommend a decent portable image storage device. I would prefer it to have a screen to view colour images with delete options if possible. Ideally around 40GB or more. I'm off to Thailand for 3 weeks in late January/early February and although I have 13GB of SD cards for my Pen and Canon G10, I think this will not be enough. Besides, I'm planning a lot of train travel there. Ideally, a lot of this time could be spent sifting through images sorting "the corn from the chaff" Thanks in advance. Dave T.
