As mobile browsers improved in capability and mobile networks improved in speed and reliability, the industry (and users) started to favour mobile sites over apps. In the last 2 years or so, mobile web usage has increased dramatically, and mobile app development became unfashionable.
Then Apple came along with the iPhone and the App Store. Suddenly it was easy to download and install mobile apps. Most serious players are following Apple’s lead: Nokia, Samsung, Microsoft, RIM, etc. So now mobile apps are fashionable again!
However, the latest twist is that with the help of standard open web technologies developers can create mobile sites that look and feel almost identical to apps. Last week Google launched the new Gmail site for Android and iPhone using HTML5 and Gears. The site is using aggressive caching, and the experience is very close to a mobile application. The most impressive thing is that it can be used offline too. You can open and read emails when offline, you can compose emails offline, etc.
The traditional differences between mobile sites and apps are disappearing quickly. For most types of mobile content, it will not be relevant to make a distinction between experiences developed as apps, and as sites.
