TN displays suffer from limited viewing angles, especially in the vertical direction. Colors will shift when viewed off-perpendicular. In the vertical direction, colors will shift so much that they will invert past a certain angle.

Also, most TN panels represent colors using only 6 bits per RGB color, or 18 bit in total, and are unable to display the 16.7 million color shades (24-bit truecolor) that are available from graphics cards. Instead, these panels display interpolated 24-bit color using a dithering method that combines adjacent pixels to simulate the desired shade. They can also use a form of temporal dithering called Frame Rate Control (FRC), which cycles between different shades with each new frame to simulate an intermediate shade. Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". These color simulation methods are noticeable to many people and highly bothersome to some.[4] FRC tends to be most noticeable in darker tones, while dithering appears to make the individual pixels of the LCD visible. Overall, color reproduction and linearity on TN panels is poor. Shortcomings in display color gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is not uncommon for displays with simple LED or CCFL-based lighting to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated CCFL or LED phosphor formulations or RGB LED backlights, may extend past 100% of the NTSC color gamut, a difference quite perceivable by the human eye.

In short: Once you've gone IPS, you never go back

To me it's not really about viewing angles...  it's rather that TN panel color reproduction makes me cringe after getting used to IPS.

Still, no matter what display type you get...  always gotta keep in mind that there are huge difference between different brands and models depending on the quality of backlighting and the electronics used to control the panel. As said before...  no way around reading a lot of reviews... and if possible checking the monitor out in a store too.

Viewing angle is also irrelevant for my buy descision. I always sit straight in front of , and don't watch TV / DVD on it. I'm still a little unsure what to buy though

Still... check it out in a store... especially if you get a TN panel... 

And don't get tempted by these cheap 26"-30" monitors flooding the market... 
Friend of mine got a "bargain" price on a 26" TN panel monitor...   and even when sitting right in front of it you can see the color shift noticably on the edges when you just move your head a little....   and when you sit perfectly still you just notice how horribly uneven the backlighting is.

With monitors... much more so than with most other products.... you really do get exactly what you pay for.

Uh, that's evil I'm still quite tempted towards the one from Viewsonic. After all, it's a good company and I'm used that they have good quality. Maybe it's not state of the art, but on the other hand, for 250,- € there isn't much damage done....
