Powering from a non-dedicated power source

The Quick Start Guide says:

Micro USB power supply – make sure you use a good quality one, capable of providing at least 700mA at 5V. Do not attempt to power your Raspberry Pi by plugging it into a computer or a hub.

If I can find a powered USB hub that specifies it will provide at least 700mA, is there any reason why it shouldn't be used as the power supply?

    Ha, I saw that, but thought it was asking something else for some reason... oh well, duplicates are still good for searchability! Have joined you in voting to close :-) – Highly Irregular Jun 12 '12 at 21:46
