I have had my new Dell Studio 1558, for just close to two weeks now and it is great.
The new Studio 1558 features, 500Gb 7200RPM HDD, Core i5 CPU, 4GB 1333 Mhz DDR2 and an ATi Radeon HD 4570.
So far battery life is about three hours and the embedded 3G connection seems a lot more stable than that of the 1555.
Right now I have got my eye on the new Dell U2311H as an add on to my workspace.
I have always liked the idea of a notebook with a big external display to be used as my digital canvas and a Dell monitor seems to be the perfect fit...
