It is becoming more and more important to optimize your website for mobile.
The Smartphone is transforming communication and publishing.

When a visitor browses to your WordPress.com blog website using a mobile device, WordPress.com will show special themes designed to work on small screens focusing on fast load times.
Some WordPress.com themes are mobile-ready, also called “responsive width”, that adapt themselves to the device of the user.
However all WordPress.com themes are already mobile-friendly by default. The Minileven theme (a modification of Twenty Eleven) is displayed on modern mobile devices.
Users using older mobile devices will see a version of the WordPress Mobile Edition theme.
WordPress.com also provides a special theme called Onswipe for the iPad.
So by using WordPress.com your website is already mobile-ready without you having to do anything.
Just another great reason why you should be using WordPress.com for building your Web Presence.
