16:9 isn't the problem really, it's the poor 1920x1080 resolution 98% of all the screens currently on sale come with. As another guy pointed out the 27" screens with their mega 2550x1440 res look awesome and they're 16:9 but don't hurt for verticle resolution.
In the 1920x market however 1920x1200 monitors are the way forward for sure. 16:9 1080p monitors are horrible. I use them at work and really hate the rubbish verticle res. I've had that same vertical res for 6-7 years now.
I can confirm this, 2560x1440 monitors are very much awesome and should be on the shopping list of anyone looking for a monitor with decent budget.
