There was nothing in the thread about Windows Phone either until you brought it up. ;-)

Fragmentation is fragmentation. The phone market may be newer, but there's plenty of experience with fragmentation in the PC. Basically it's a big headache for MS and can be for users as well if something breaks- e.g. one of the updates messed up the video drivers on my PC last year. IMHO people only tolerate updates because of the security risk and many of my customers deliberately keep old OS for their own reasons.

Why are people determined that keeping the OS up to date suddenly will be a major priority for a phone user? If big security holes appear, obviously, but otherwise what's wrong with a device that just works? It's a very clever job that the blogger did documenting Android fragmentation, but unless people believe there was a simultaneous lapse in competence by the most successful phone manufacturers on the planet, perhaps there's more to the story. I've made a suggestion: if you're determined that it's wrong, that's cool.
