If weight is a primary concern, then ultraportable is the way to go. For most people, a 5lb laptop isn't considered heavy. The D810 is about 6, iirc.
As for your processor question, ultraportables use low or ultralow voltage pentium-M, while mainstreams use one of the regular pentium-Ms. Either will handle standard notebook tasks like browsing the net, email & office apps. If you're planning to do something most processing intensive, you should consider a mainstream system like a Thinkpad T or R series.

The T's are light and powerful, while the R's are slightly heavier, but tend to give you more bang for the buck($).
Hi,
I am trying to ducide between a Dell X1 and D810. I would like to hear from anyone who has either for some advice.
The issue I have are as follows. I unsure about the processor on the X1 as it is only 1.1ghz compare to the D810's 1.86ghz. What do people think?
The other issue I ahve is with the weight/size of the D810. It is 2.94kg's in weight and I have read on different sites that people find this too heavy.
I would really appreciate any views on this as I am very confused. I know I will have to make a tradoff but wonder which one. The price of either is similar, around $2141.
An outside runner is the D610.
Any help please?
