If it is true (& everything points to that), Motorola (Lenovo), absolutely should be ashamed.
For the price one major update is still good however they won't be able to keep that up as well because of releasing multiple variants of the same device this year.too bad.
Given lenovo track record on updating their device and the fact Motorola owned by lenovo, this hardly a surprise.
It's just tragic what happened to Motorola. Lenovo fired most of the Chicago staff. They went from being the best vendor for upgrades to THE WORST!
