Ive tested several tablet devices and have found the Lenovo Thinkpad Tablet as the most versatile for business use. With a built in stylus for hand writing recognition, slots for 3 different size memory cards and a sim card, full size USB, a great keyboard with an optical trackpoint and mouse buttons, it has great flexibility. It also comes with a registered version of Docs to Go, McAfee Mobile Security, and several other apps for printing and connecting to cloud based services. It also has a slew of managability features including the ability to login using Active Directory credentials.

Though it is a little bigger and heavier than my iPad, Im replacing the iPad because I feel the extra flexibility is a good trade off.

I'm not using it or trying to use it as a laptop or desktop replacement and have no intention to. My take is that its a good supplement, otherwise I would just use my laptop or desktop...
