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
Step 2: How to Do It
Basically I just plug the memory card in to the adaptor which is attached to the back of my PDA.
The adaptor I used will allow me to copy SD, MMC, sony memory stick various versions , XD Micro SD and probably others as well.
If I want to copy CF cards I just plug them directly in to the CF slot. So no need for the adaptor.
Open a file manager and copy the files to the second memory card.
when the photos are on my PDA I am then able to email them to facebook or picasa if I wish.
Step 3: Extra Infomation
I have seen USB copying devices the only problem with them are you cant see what you are copying. You are unable to free up space on the memory card if needed.
you are unable to edit and email the files to facebook without going to an internet cafe.
I also have an ASUS wifi wireless Hard drive which gives me 40GB of storage.
So I can transfer Photos, Video, Music and so on to that.
plenty of space for music and video while on holiday.
