Does this work for the 550D/T2i?
 

Canon DSLR Video Monitor for FREE Using your Laptop

Canon DSLR Video Monitor link!

Yep, standard feature of Canon's EOS Utility software that ships with the camera.

That is awesome! Except now I WANT to travel with my laptop to use as a monitor! Arrrrgh!
More stuff to haul around!

The video shows use on a laptop, and he talks about his netbook, yet does not explain how netbooks (and laptops) can work with larger-than-actual desktop sizes. Not ideal, but there's plenty you can do with a 10" screen running virtual 1920x1080.

As I plan to use with my 17" MacBook Pro, it should show large enough to be useful. I will post back once I check it out!

It works GREAT! won't go full screen but as you resize the window, it grows. I'd say about 90% of my 17" was filled. And sharp enough to do follow focus work!
AND the viewfinder on camera stays on!

Wouldn't it be incredible if they released an iPad app that had the EOS software? Then I could justify getting one! :)

hmmmmm...let me talk to a developer friend who does apps!

Yeah, I wish the iPad would take an external video input signal, would be sweet to use as a monitor on shoots.

Well, if it could run the software, just need a usb cable!

Hmm, the iPad works with Wi-Fi and the T2i accepts Eye-Fi cards....

The iPad doesn't have a USB connection on it...to my knowledge...

There will be a USB solution that plugs into the dock connector, Apple already showed it in the iPad's introduction, although it's meant for uploading photos from a camera. Don't know if that can be harnessed for this purpose, but that would be mighty fine!

Yeah, I assumed it would connect like iPods via USB.
