That monitor is awesome, got one back at home - really impressed.
If you want multi monitor - that is one of the best options around.
They are not in stock right now - but I think some new ones will be available in the week.
They are not bad, just like a 7800GTX is not a bad graphics card (as it can do what its designed to do well) - but compared to the more advanced tech stuff it pales in comparison. If you want an appreciation of the difference, use an IPS or VA panel for an hour, then go back to a TN. You will then be able to tell the difference.
