Since you are from the UK, you might not understand. The #1 (verizon) and #3 (sprint) cell carriers are CDMA, and they are not going away, or becoming "obsolete" as you put it. There will be movement to 4G in the next few years, but 3G and 1X will not just "go away", it will still be there.
10 years is a lifetime in world of electronic devices though, it may just be that no one will even want to use a Kindle 1 then, and if they do, they can just hook up the old usb like everyone else does. It's a given that the ereader market is going to evolve and go thru some drastic changes in the next few years, but I think you are being premature in writing off these devices now. They are actually very useful, and will probably remain so as long as they can pump the electrons, so to speak.
