Unfortunately the only place most people can see an IPS panel in person is the Apple Store, and their displays are glossy (iMac, Apple Cinema). You could try looking at Panasonic LCD televisions, although those are obviously much bigger and are made by IPS Alpha (not LG.Display, which manufactures 'computer' IPS panels). But it might give you an idea of IPS v M/PVA (the other brand-name TVs in a shop will probably be PVA panel).
If you're used to M/PVA, you should know that IPS panels generally offer less impressive blacks and weaker contrast. Colours won't seem as bright, though they may be more 'accurate' (true to the intended image). I believe one of the reasons Apple glossifies their displays is to improve apparent colour brightness and contrast.
Some punters also find the anti-glare coating (which can appear like a speckling or dust on the surface) very obtrusive. Anecdotal evidence suggests the coatings are getting more aggressive on recent Dells. The coating on my Dell 2209WA doesn't much bother me, but I can certainly see it if I look for it.
