1.) My 18 month old 635 is not an ancient and obsolete device by any sane stretch of imagination. But maybe in the heads of marketing tossers in the IT companies it is. Since it has the 1/2gb of memory it will not apparently update. Maybe that's a good thing, but that's beside the point.
2.) ", this probably won't matter to most 520/630 owners, who are very unlikely to be tech enthusiasts and won't even be aware of any further upgrade possibilities...." So this "tech expert" presumably thinks that " tech enthusiast " is the same as fashion following sheep that only want the latest shiny shiny.
God help the industry.
