What Differentiates the Touchpad from other tablets

Touchpad Differentiators:

• Great Virtual Keyboard that's re-sizable, has a number row, next field key, and easy character accents
• Flash 10.3
• Cards/Stacks visual multitasking instead of task switching with only icons
• Synergy system that integrates multiple accounts
• HP printer drivers pre-installed with wireless network printing
• Up to 16 Exchange and other 3rd party email accounts at once
• webOS Profile Cloud Hosting  Environment Connecting Multiple Devices to One Profile
• Accepts Texts and Phone Calls from phones on the Touchpad
• Touch-To-Share data transfer with webOS smartphones
• Touchstone Charging  Dock that can charge the Touchpad even with its case on!

Here's a great video demonstration of the Touchpad: 

You can see that webOS runs on the Touchpad without the lag it had at the February 9th event.  The only thing I noticed slow in the presentation was the video streaming - which can be attributed to a slow network connection.
