Does anyone have experience of High Gamut monitors?

For the last several years I have relied on an (almost) matched pairs
of Dell 2410 monitors - and now one has died. Not really surprising,
considering it was +8 years old, but it was a bloody good monitor. I
am now faced with the task of replacing it.

I don't want to just replace it as it would amount to no more than
installing 8 year old technology and I have been frantically beating
around the bush trying to decide what to do. I am considering all
kinds of options but I don't want to go into them now. One possibility
which is raising sweat to my brow is the use of a high gamut monitor
such as the Dell Ultrasharp 25 UP2516D

or http://tinyurl.com/hdpepts

My reading on the subject suggests that monitors such as this can have
problems with non-color-managed applications such as many that can be
found on the Internet and can also create problems when editing images
in all kinds of software. I would like to know if anyone has had any
experience with such monitors and what their comments may be. Should I
consider them and, if so, with what caveats in mind?
