I'm away from my home office fairly regularly but I find it difficult to really settle to productive coding without my custom 4-screen custom built PC. My laptop (a slightly ageing HP Pavilion with a 1440 x 900 display) would really benefit from a portable monitor to plug into the vga port. Is there any suitable products out there which offer an easily luggable lightweight monitor which would fit in my laptop, offer reasonable resolution and response, and significantly enhance my screen real-estate?
