Let the hive mind of Engadget get that for you.
"I'm pretty much a complete noob when it comes to camera stuff. My wife loves to take pictures, though. So much so that she literally wore out her first point and shoot camera, and the Kodak Z712 I bought for her less than two years ago is starting to act up as well. To compound the matter, we are expecting our first born sometime next year. I fear the Kodak just isn't going to cut it any longer. What would be the best starter DSLR to get? She hates missing photo opportunities due to camera 'lag' so speed would definitely be at the top of the list. Photo quality and features would be next. Price should be no more than $800. I'm not interested in video capabilities."
I'd love to upgrade but one thing I don't see is how many phones the base station supports and how to obtain additional phones+cradles.
If this is a 1 phone deal then I can't see much of an upgrade path (excepting the benefit of being able to shut down my PC)
Has anyone seen any information about whether or not it supports multiple handsets and how to obtain them?
