Today’s smart phones (i.e. phones with an OS capable of email and more) supplant the need to lug your laptop with you during your travels. If you simply need to read and respond to emails, surf the web, or stay in touch via Twitter, Facebook, or other social networks you’d do well to consider a smart phone. There are literally thousands of apps out there designed to help you do the things that interest you while you’re on the go. You’ve got mobile banking, blogging, and GPS apps that happily connect you in more ways than ever. Simply put mobile apps allow you to get things done sans laptop.
