This is one of the easiest reviews I've ever had to write. 

Everything Lenovo says about the X61 is true.  If anything, it's understated.  The X61 and Windows Vista Ultimate have given me what I've been looking for for some time - a Tablet PC that runs Media Center well.  Yes, I use an external card, but that's a small price to pay for something I've waited 4 years to work.

The system is snappy, reliable and does it all.  This is my everyday machine and it goes with me everywher.

X61 Tablet: Choice of Screen Technology to best suit your needs

X61 Tablet MultiView + MultiTouch

The touch panel has super low reflectance technology by adopting “Circular polarized construction” technology to improve screen viewability drastically both indoor and outdoor.

MultiView provides clear screen image indoor, and low reflectivity outdoor even in sunlight.

ThinkPad X61 Tablet has digitizer at LCD back side to recognize electromagnetic stylus pen (excellent pen input usability, same as X60 Tablet), and touch panel in front of the LCD to recognize finger input.

Conventional touch panel notebook has a touch panel in front of the LCD.
This means that there are 5 reflectance layers, which generate much reflectance.

NEW SXGA+ Screen with “Direct Bonding” Technology
Direct bonding technology offers significant benefits over similar panel technologies:
Improved readability outdoors especially in sunlight
Lowest reflectivity
Less susceptible to scratching
More durable under harsh conditions
Lighter and thinner design

Both screen choices have dynamic screen orientation capabilities.
