There are a few wireless devices comming onto the market to allow the tranfer of photos directly to your laptop by using a wireless conection. Has anyone setup such as system? Have you seen this video?

USB wireless is a standard from 5 years ago already but it never did catch on, those devices are nothing new at least.
I've never used one since I don't have need for it, I wonder how useful it is for camera use...

I think the way to go is the eye-fi cards.

Haven't tried them myself though.

All the latest Pentax compacts have Eye-Fi capability.

Surely most computers including laptops have card slots in them. (Mine have). So to me eye-fi seems like technology gone over the top a bit. CHEERS Vic.
Born again biker with lots of Pentax bits. Every day I wake up is a good day. I'm so old I don't even buy green bananas.

It would however stop you leaving the card in your PC's card reader and sauntering off with a card-less DSLR (Something I do all the time!)

AFAIK, the transfer rate is acceptable for JPEG, but a killer for RAW.
That puts me off it

Matt WUSB support 480 Mbit/s at distances up to 3 meters, fast enough for most RAW shooters, if you don't machine gun with the K7 that is.
It should keep up with all the other Pentax models machine gunning.

Stefan,
I'd be cautious - it's usually up to 480 Mbit/s

For example, I have a Freecom NAS drive that has a Gigabit Ethernet connector.... but the CPU in the NAS can only achieve a tiny percentage of that (not even maxing out 100-base-TX ) It almost might as well be 10-base-T

Last time I looked at a SD wireless card the actual transmission rate was dire

Agreed. Even a bog standard wireless router will never achieve anything close to it's theoretical maximum. Wireless G units usually max out at around 40Mbps (instead of 54) if the receiver is right next to the transmitter. The greater the distance and more walls it has to go through the more the speed drops. Then you get things like your telephone, radio and microwave further slowing the signal down. In my house I'm lucky to get 30Mbps on my G network, and my N network i usually get around 50Mbps (theoretical max of 300).

Just looked in into the matter more, I believe what you end up with with pure speed is 100 Mbps, that's still almost a raw file per second.
They said that with a good integrated system they can up it to 200 Mbps at close range, that's good enough for most users.
Sadly it would take a long time before we might see such WUSB system, it hardly catch on and might be outdated quite fast.
