It's been quite a while since we've seen a new Classmate PC from the folks at CTL, but the company's now back at CES with a pair of new models. Those include the 2go Classmate PC NL3 convertible tablet (above), and the 2go Classmate PC E12, which takes on a more traditional laptop form-factor. Both models pack a 10.1-inch screen (with the NL3 employing a resistive touchscreen to accommodate a stylus), and each boast some relatively similar specs across the board, including a 1.6GHz Atom N2600 processor, 1GB of RAM, and your choice of either a standard hard drive or SSD for storage -- plus the same ruggedness found on the company's earlier Classmate PCs. Look for both to be available early next month, with the NL3 starting at $499 and the E12 coming in at $349. Videos of each are after the break.
