Dell begain pre-order page for the touchscreen convertible that you've been waiting for: the Latitude XT3. The Dell Latitude XT3 was announced all the way back in February of this year. Since then, Dell has continued to sell the Latitude XT2, a 12″ Tablet PC. The XT3 is a convertible Tablet PC with a 13.3″ display. In recent years, the larger PC manufacturers have shunned 13″ and larger Tablet PCs in favor of more mobile offerings.
