Panasonic ToughBook C1 gets upgraded with faster processor, better battery life

It may not look any different from the outside, but Panasonic has made some not insignificant upgrades to its rugged, 12.1-inch ToughBook C1 convertible tablet. That starts off with a new Intel Core i5-2520M vPro processor (2.5GHz, Turbo Boost-able to 3.2GHz), along with a standard 320GB 7,200 rpm hard drive (up from 250GB before), and some improved battery life -- Panasonic says you can expect twelve hours from a pair of hot-swappable batteries, or six hours with one. It also says its various improvements contribute to a start-up time that's 30 percent faster than the previous model, although that will obviously vary in real world use. Somewhat unfortunately, the convertible's base price tag has also seen a slight upgrade -- it'll now start at $2,599 instead of $2,499 when the new model rolls out next month
