The number of average people who would be willing to upgrade anything on their computers is tiny. Again, I personally am all for these devices, but as I mentioned even on a desktop PC, where upgradability has been cheap and easy as hell since essentially the beginning, few regular folks do it. Tech people are going to think this company and it’s products are a slam dunk, but I think in the regular marketplace they will see a lot of people scratching their heads asking “now why would I want to do that?”.
