It's hard to overstate how cool extended battery life can be. I replaced the batteries in my old Newton eMate with some modern NiMH rechargeables, and now get over 30 hours of continuous usage. In practice, that means I need to recharge about once a month. That makes it an awesome device for backpacking, mountain climbing, adventuring anywhere you won't have an outlet.
