MSI today also starts the new U123 netbook line-up composed of the U123, U123H and U123T machines. U123 series netbooks are light and compact, they fit into an A4-sized bag, but come with a relatively large screen and keyboard. All four models have very nice exterior design and can be purchased in four different colors - pearl white, dolphin gray, midnight blue and silver red. Further more, U123 series use the latest Atom platform from Intel, a 80 GB, 120 GB or a 160 GB 2.5-inch SATA hard drive, 1 GB on-board DDR2 533MHz RAM (up to 2 GB) and although the name suggests a 12-inch screen, all models have a 10-inch LED backlit display with 1024 x 600 native resolution. No detailed information on the difference between the three models is published, MSI only mentions that the U123T integrates a TV tuner, the hard drive space varies between models, and that the U123H has a 3.5G HSDPA module.
