They released some new models of their Visor line of PDA's and are the only people allowed this year to actually sell their products right on the floor. On this same line, Microsoft is taunting us with their PocketPC's. In partnership with other companies such as Compaq, MS is producing these small PDA-type units that are actually quite nice. The color capabilities of these screens are awesome. The trends are interesting, but each company's basic offering is nothing to write home about.
Products use new interfaces, look sleeker, get smaller, but nothing staggering.
