Whenever I see people saying this, I wonder how many people actually use their computer to do real work.
I work as a recording engineer. You can buy non-PC devices to do the actual recording if you want, but even in that case mixing and post-processing really does require a computer with vast amounts of local CPU power and storage, in addition to some highly specialised equipment (such as external audio interfaces that connect via Firewire or even PCI cards). You can't record ten simultaneous tracks of uncompressed 24-bit, 48 khz audio to the cloud. I'm sure the same is true of many other fields like video and graphics production, software development, and scientific number crunching.
Sure, grandma probably doesn't need a full-blown PC to look at emailed pictures of her family, and maybe the "post-PC" era will benefit her. But I do worry what will happen to the PC world if major manufacturers keep taking their focus away from people who really do require serious equipment. (Hello, Apple, selling 2010 Mac Pros for 2014 prices, with an operating system that's leading the charge towards turning your desktop computer into an iPad!)
Except that this case deals with the Galaxy Nexus, for which Google controls the updates directly.
...so I don't *think* Android...
2.3 is over 18 months old so I don't Android is incrementing terribly quickly.
