I would go for the acer, as i can live with the smaller one inch screen, and even so most time i wont be out using my laptop for 6 hours or so.
the HDMI would act as a huge plus as i would be able to plug it into any HDMI equipe montier, where as the VGA plug has become ver obselete and also, very poor quality.
Acer all the way, since i can plug it into an even bigger screen!
