Anyone recall how many 500's were sold? 10,000? I thought I read here that it was a bit of a surprise to Sony that it turned out to be that high. For a device sold in a fringe market (okay, an up-and-coming market) that's been out less than a year, I don't think they're going to stop supporting it with that kind of base. Also knowing that the people who bought them are the technology's biggest supporters. And really, the word this week seems to be that the 505 is a nice but pretty minor model improvement with the the improved e-ink display being most notable. I assume that's not a big change (in terms of support from Sony). Two firmware editions for them to maintain? Big deal. And Adobe Editions for all of us. So I'm guessing (let's see....crystal ball, crystal ball) we're safe until a really major model change happens....uh, in 2009....er, July 12 to be exact. So there!
