I got rid of my laptop after doing several 5 cities in 4 days business trips. I took a look at what I was really using my laptop for and it didn't make any sense to lug it around airports, go through the hassle of security and have to worry about having it stolen just for checking e-mails, internet access and editing documents and schedules.
So I got rid of it and purchased a smartphone. It enables me to check e-mails, surf the internet, and it also has Word,Project, Excell, Powerpoint and Adobe Acrobat plus I have worldwide cellphone access and it fits in my pocket!
