Q: I want a digital frame to show off my photos. Can I get one that doesn't cost a lot and works with the Wi-Fi network in my house?
A: Digital frames are hot, with dozens of models to choose from. Most have slide show modes, remote controls, video and audio, and multiple card readers -- but there are some big differences in screen size, resolution, performance, and extra features. Most don't have Wi-Fi. And that can save you a few bucks.
