When I'm on holiday I like to back up all the photos a take. and to sort out which photos to delete. and upload the good ones to facebook.
The only thing is when on holiday I don't want to lug around a laptop.
The solution I have found is to use a PDA with a compact flash slot.
And I'm able to back up all types of memory cards.
Step 1: Equipment needed
1 PDA with a compact flash slot ( you can get these very cheaply on ebay now)
1 Compact flash card adaptor
some memory cards
