I had been on the lookout for a Dell 23 inch monitor to go on sale. However, the 21 inch has gone on sale instead... with a coupon I should be able to get it for $188 or so. Is 2 inches going to make much of a difference? Both are IPS.
Here are the specs... http://accessories.us.dell.com/sna/productcompare.aspx?k=ips&category_id=6481&c=us&l=en&s=bsd&cs=04&nf=1253~0~272388&prods=320-9270,320-9271
