"most Android phones quickly end up with outdated versions of the software, and get stuck there. It’s left the Android market deeply fragmented.
Even when Android handsets do get updates, it can take eons"
7 of the 18 Android phones never ran a current version of the OS.
12 of 18 only ran a current version of the OS for a matter of weeks or less.
10 of 18 were at least two major versions behind well within their two year contract period.
11 of 18 stopped getting any support updates less than a year after release.
13 of 18 stopped getting any support updates before they even stopped selling the device or very shortly thereafter.
15 of 18 don’t run Gingerbread, which shipped in December 2010.
In a few weeks, when Ice Cream Sandwich comes out, every device on here will be another major version behind.
At least 16 of 18 will almost certainly never get Ice Cream Sandwich.
