I just ordered the Dell UltraSharp 2407FPW days ago and it's on sale at dell.com. If you are a Costco member, the price is about the same. Anyway, it comes with 3-yr warranty, which is nice.
Apple display is nice, but limited to DVI output.
DVI KVM switch (e.g. IoGear) is possible, but if you hook up an Apple keyboard, I noticed that not all Mac-centric keys will work.
