“But what if you fill your available cards and you’re not near your laptop? Then you’re out of luck.” Not if you’ve got three more SD/MS/whatever cards in your bag weighing almost nothing and far quicker to switch than to deal with this device.

The best use for devices like this is *not* the example you give. Two scenarios where this is actually useful:

1. You throw a large party (a wedding, for example) and at the end, you have a few of these near the exit. You can ask your guests if they’d be kind enough to share the pics they took at the event and get to take home many photos from all around the party of things you might have missed.

2. You’re out on a day trip with a bunch of friends. At the end you can quickly collate everyone’s pics and have them in one place for creating a comprehensive album or DVD for everyone.

For the individual with one camera this is entirely pointless (in my less than humble opinion).
