The Tech Report had a handson experience with the new Intel Classmate PC convertible tablet at CES 2009. This unit uses the Atom N270 1.6GHz processor and has a 8.9" touchscreen with a 1024 x 600 pixel resolution:
Like the previous clamshell design, the convertible Classmate is based on the Intel Atom processor, the near-ubiquitous netbook platform. Specifically, the convertible Classmate uses an Atom N270 processor at 1.6GHz and a 945GSE chipset, and Intel claims about 30% longer battery life and 50% higher system performance for the new model. Battery life should be around 3.3 hours for the four-cell battery and 5 hours for the six-cell. The touch-sensitive display measures 8.9" from corner to corner and, like many netbooks, has a 1024x600 resolution. Storage comes in the form of a 60GB, 4,200-RPM Samsung hard drive, and the whole system weighs in at just 2.8 lbs. in the default configuration.
