Something I will miss from my Palm m515 (I know it will be replaced someday) is its metal body. The 2210 fits the hand, that's true, but feels "false" too.
I understand this tendence to flee from metal housings is in order to reduce weight, but for someone like me, who works in an environment harsh for electronics like construction, it is better to give up lightness for body hardness.
In the end, how many people are keeping the handheld in their shirt pockets so as to make weight so critical? I wear it in the belt, but even if you keep it in your hand and with a case, handheld's weight disappears as an issue.
