If there's any office software which is designed for touch than traditional mouse+keyboard , that will be great .I need to deal with office files on daily basis , which is the main reason for me to have a decent laptop . If we call Nokia N900 is mobile computer , touch design office is needed to be worked out . Other than that , most of my daily work and personal stuff can be resolved with N900.

The other thing is battery life , do not make me bring two extra battery with me for a one day heavy usage . I got the feeling that we might need that amount of spare batteries when final release .
