Need computer help!

...and my centrino battery life is 5 hours or more. It's a Dell Lat 5500.
I've never been crazy about Dells, but this one's nice. The new 5520 is NICE but big (and $$$).

Our Lenovo rep has been trying to sell to us for years.

I used to work for IBM (which spun off the PC market into Lenovo), and they were HORRIBLE to work on.
However, the rep told us that they just got out from under the IBM design and supply commitment, and are no longer forced to use IBM parts and designs.
He shoed us a "mid-sized" notebook that is in between a tablet and a laptop, and it rocks. Great compromise in size and it has all the hardware i/o our 40,000 unit plant wants. Everyone who saw it liked it.
