I'm looking to buy a laptop and my primary concern is that is has a long battery life. It's for school and I'll need it to last throughout the day without a recharge. It'll only be used for word processing. So far I've come up with: Sony VAIO® TR3AP1 Notebook w/ large capacity battery and Panasonic ToughBook CFW2 I read that both have a battery life of ~6 hours. Does anyone know of other options? I'd like something cheaper because the two above are around $2K.
