I got a Huey Pro a couple of weeks ago and I've got to say I'm impressed with it. For those who've not played with one of these things before it's a gadget that sticks to you screen and builds a colour profile of it so you get a more accurate display. I've no idea if this Huey thing is itself accurate or whether there are better things out there (I got it because it's well supported in linux) but the difference it can make on some screens is amazing.
I've been trying it on every screen I've come across, mostly cheap TN panels and on them you see quite a change. My old acer netbook seemed to the furthest out of all. However you can't make a TN panel anything other than a TN panel. The other day I used it on a Macbook pro which I assume had an IPS panel... If I really was looking at a properly calibrated IPS panel then I'm totally sold on both this gadget and IPS panels.
It looked pretty good before I calibrated it, but afterwards it just looked fantastic.
I'd suggest any photographer types looking for a new gadget to spend money on need look no further
