Depends on what you use your machine for.
Webpages are long and some spreadsheets have lots of rows, so a WS may not be as desireable.
You would need a 1680x1050 or better WS to get the vertical pixels of a 17 or 19" standard LCD. You would have to buy a 24" 1920x1200 WS just to get the vertical pixels of a 20/20.1 standard LCD.
For today's games, landscape photos, WS video and spreadsheets with lots of columns a WS is great.
I use a 22" 1680 WS myself and I love it. Some games you have to edit command lines, ini/inf files and hack the fov which sucks. But it is nice having more peripheral vision in games.
A WS that tilts can provide the best of both worlds. You can often fit an entire webpage on the screen when they are rotated, see entire documents and get a ridiculous amount of spreadsheet rows on the screen at once. We have some FPD-2185W gateway LCDs like that in our shop. Very impressive.
