Usability 
Personal portal site, Netvibes has launched optimized "Touch Web" versions of the site for the iPhone, iPad and Android. Rather than using a single URL and browser detection to optimizing the site to each platform, Netvibes provides separate URLs;
iphone.netvibes.com
ipad.netvibes.com
android.netvibes.com
for each platform. The appearance, UI and content of all three variants appears identical although there are undoubtedly some behind the screen optimizations for each.
According to NetVibes, the sites deliver a seamless experience across desktop and mobile with real time synchronization of read/unread items across platforms
