I haven't played with the Y-Series yet, but in general I like Lenovo laptops. This is the least expensive Y model I would look at:

It has a Core 2 Duo processor (only 2.2 GHz, but that should be fine for most people I think), 4 GB Ram, 6-Cell battery and 1 year warranty, If you got the cash, this might be more to your liking, I'm just not sure the upgrade justifies the price difference from the other model:

The Dell Inspiron 14 is fine. However, if I were going Dell, I'd look at the Vostro line from the business line. This is a good deal, IMO, but is a little bigger than the 14:

In my experience the business models (essentially the same as the consumer line) seem to be slightly better constructed and you can get some very good deals. Based on a quick look, it doesn't seem like the deals are as good as usual today.
I'd also consider HP and Sony laptops. You can sometimes find very good HP deals.
I'm in a hurry now. I'll do some more checking for deals when I get back tonight, if you haven't made up your mind yet. In the meantime, my advice is to make a Core 2 Duo your minimum acceptable processor. If you can wait another couple of months, Dell will be blowing out the Core 2 Quad and maybe even the Core i5 machines...or so I hear.
