I see your point about planned obsolescence and agree, but the race to bigger, better, and faster takes care of it for us. For example, out router is not IPv6 capable, but version 2 will be when it comes out of test early next year. It will also have many other capabilities that no one has, at least not in one 15cm x 25cm x 6cm, 12W consuming, box that mounts on a wall and is administered by a web page.
When we release this gem, we have literally 15 other projects in the wings. We won't loose market because we don't narrow it to one. We raise the bar in one market and move on.
