With decent monitors in the setup it’s not a particularly cheap option, there are bezels to get in the way and 3 power cables to consider. Some have taken to setting up multiple monitors in an Eyefinity or Nvidia surround type setup.
For some users, though, even 16:9 is too square and they crave even more width. Some people enjoy the widescreen experience, others crave more relatively vertical space and cling to 16:10 where possible for widescreens. Widescreen monitors are now omnipresent, with the 16:9 aspect ratio the current mainstream standard.
