I'd say if you are looking to upgrade your system with monitors, that now is a good time to do it. I'm seriously considering picking up another 17 inch so I can finally do my multi monitor setup. $215.10 for 17" monitor on Dell's website. http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=320-4567
Oh yeah, very true. I just bought a 17", the 19" are too big for my desk. I might only be able to fit three 17" monitors on my desk. 19" are getting very cheap as well like you said.
