The Asus Eee PC T91 touchscreen tablet netbook was announced at CES in January of this year with Asus hoping to repeat the netbook revolution it started with the Asus Eee PC 701 but this time with an Eee PC that has a touchscreen which can swivel around to turn it into a tablet. The T91 went in sale in the USA this week and should reach the UK soon. The question is should you buy one or stick with your iPod Touch?
