only 50GBP? thats not cheap at all. you can get CF adapter and, say, 4Gb CF card for far less.
yes, 4Gb is a lot for some of us.
granted that ssd, might be more 'robust' as its designed to work as hdd.
another problem is that they are not easy to find. well at least not for me, and additional costs like postage and customs are not small. such a shame, I'd use one in laptop.
