I read on the Motion Computing site that the 915GM chipset which comes with only four tablets that I know of: LE1600, SC3000, X41, tc4200; will allow your hardware to upgrade to MS Vista coming in 2006. To my knowledge, I have not seen any of the newly introduced tablets come with the old 855GM chipset. For those of you who don't know, Vista will introduce the stylus to the world at large. There will no longer be a need for MS XP Tablet Edition. Computer sales will hit a record high in the next 3 years because Vista requires that the hardware have an active digitizer in the monitor as well as a stylus to make full use of all its functions. Although, it might not be named Vista in the future as there is currently a trade mark dispute over the name. Oh Bill, dear Bill. This is just an FYI for those of you buying new equipment. Pen Computing has a layout of over 20 tablets this month including the chipset used by each. If you're planning on upgrading to Vista, once released, be aware.
