Imagine waiting for your upgrade option with your mobile carrier, opting for a “new” Android phone, only to find that you are looking at the old version of Android and all of the limitations it comes with regard to installing new apps.
The biggest problem with this is the fact that using older versions of Android can mean skimping on the latest Android functionality seen with phones using the latest version of the mobile Android platform. Yes, you still have access to the Android market place. And to a degree, I suppose many folks are not all that concerned about this.
However, when you consider that most folks are buying a new phone simply because they are looking to get the latest, it might be sort of nice to have the latest OS available with that upgrade. Sadly, though, this seems to be a missed ideal with many phone manufacturers and mobile carriers. So buyer beware.
