As a heads up, when dealing with these ULV processors, you will likely notice a performance boost in the 1.4GHz computer, and this is the newer model, which is likely why it costs more. But as with Chris, I'm not sure that the $100 price difference is worth it (assuming that all of the other specs are the same). If it were a $50 difference, I'd likely pay the extra, but $100 is a bit harder to justify. You can always see if it goes on sale, but then the older model may not be available by then.
And to further what Chris stated about his concerns regarding the ULV processors, don't expect them to be as fast as a normal laptop processor, but so long as you are simply using it for writing notes, accessing the internet and the such, they're quite acceptable. They have a lot more power than the Intel Atom processors found in netbooks and accordingly, they will be much faster than netbooks, and they can handle multitasking much better than a netbook as well.
