Question about which processors and voltage

[venom600]

I'm looking to get a IBM X40 and was looking at the processors.

I'm wondering is there a difference in voltages and battery life?

There is a 1.0 GHz, 1.1 GHz, and a 1.2 GHz processor

I guess my key question is, is there a big difference in battery life?

Links to related to the topic are welcome

Thanks

Their is a big difference in the processor itself, but not really the speeds. That sounds confusing.. basically, if you get say a pentium 4 m, then you could really get any speed in that range or processors and their shouldnt be much different in battery life. I would definately go with the faster 1.2 as it would be faster and battery life would not be adversly affected
