Ask HN: Good portrait-mode monitor for coding?

I'd like to buy a new monitor that I'll use primarily in portrait mode. Do you have any suggestions?

Some requirements: 1) Good for reading text in portrait mode. 2) Reasonably wide viewing angle

Am considering the Dell U2312HM: http://accessories.us.dell.com/sna/productdetail.aspx?c=us&cs=19&l=en&sku=320-2807
