I just implemented AJAX techniques to allow user-friendly visual
selection of mobile phones for use.
Check this out www.mobilemediacentre.nl/en/registration

Click on the cell phone icon, there will be an in-line popup.

I used Graybox to do this. You can select the cell phone manufacturers
on the left hand side, and choose your type of device in the middle
frame. When the mouse hover the device image, product functionality and
compatibility of the chosen device will be displayed on the right side
under the device image.

All cell phone info is retrieved from database. After you selected the
device, you will be linked back to the registration page and see which
device you have chosen.

I have so far got some remarkable feedbacks:
make the information popup only popup when it is clicked. (The i -
image). Since an accidental hover may cause an unwanted popup. You could
just use a tooltip saying, click for more info etc.

Well, the original idea behind the auto-popup for the info button is to
give the site viewers a simple and ease expression; they don't have to
make the unnecessary click if they don't want to. It's also very true
that viewers will get annoyed by accidentally hovering the INFO icon
over and over. Please vote for your favorites or you have better idea?

Any suggestions are welcomed.
