Translation: Android users are at the mercy of hardware manufacturers and carriers.
There's nothing stopping a manufacturer from developing a good track record with an Android phone, but so far most haven't. Developing such a reputation could be a strong competitive advantage for someone making Android phones.
Apple can do that with the iPhone and Google can do it with their Nexus models probably because they don't release a bazillion different phone models in a year (like HTC/Motorola/etc...).
You would still have to root it and get a rom that works on that model.
