Are you familiar with any of the models that are controllable? We would like to use it like the old traditional photo album where you can sit it on your lap with some friends and go through the pictures at a varied pace by clicking/sliding for the 'next' picture.
All of the frames I've used so far have the manual viewing and automatic slideshow functionality, although how easy it is to use varies. I'd expect branded (eg Philips, Sony) frames to be easier to use than non-branded.
They generally won't work too well on your lap because most will need power and the viewing angles aren't great, but you can place it on the coffee table and use the remote control.
I'm starting to look at the Samsung Galaxy Tab now, anyone with experience of using this device?
I got this yesterday and I am very impressed. It comes with a call plan, has front and rear-facing cameras and overall the thing is very stable. I have loaded this with videos, games, e-books and music and it is handling everything I have thrown at it. A perfect size too, really. Skype voice call is out and the quality is excellent - Skype video is out shortly (allegedly). Really top banana.
Sure, and then in 6 months there'll be an Android 4.0 on a quad core tablet with a gazillion gigs :-). Reminds me making the wise decision to buy VHS over Beta then years later resisting buying a minidisc player!!
