There's a difference between change for commercial marketing purposes and progress.
Milo, your new PVR will allow you to pause live tv while you get up to do something. I'd never buy a tv with a dvd included. Disc players can break easily and you can buy one for $30 these days.
My smartphone is a discman, a weather girl, a street directory, a web browser, an organiser and a gameboy all in one.
New HC will allow you to edit your post, address another poster specifically, post easier charts, see your followers and have a swish avatar.
That's progress.
The other side is Apple making every version of their devices slightly different dimension wise so everyone has to buy the accessories new as well.
