When it comes to framed photos, families are prone to show off printed images under glass sooner than digital versions on LCDs. That could be changing, though, as prices of digital picture frames sink to new lows. Take the versatile DPF-A72N/B Digital Photo Frame from Sony. The 7-inch screen used to be priced at $99.95. Now, with a $45 instant rebate, you pay only $54.95. The offer ends on June 20.
