When the Apple iPhone was launched in 2001, the whole world (including the U.S.) was concinved that smartphones will be hot products for many years to come. A year later, Google introduced Android operating system that was a big hit in 2010. Established smartphone software contenders, Nokia, Blackberry and Microsoft developed new software versions but failed to restore their former successes. What will happen next?

Even though Nokia, Samsung and Sonim have introduced multiple mobile phone models that can stand the weather (waterproof and dustproof phones) and minor bumps, we haven't discovered decent smartphones designed for outdoors use.

Most ebook reader devices are built on E-ink display technology. E-ink is perfect for ebooks because it has been designed with high contrast black-on-white text, flicker-free reading experience in mind.

However, one thing has been missing from E-ink displays until now: colors. Hanvon has introduced world's first ereader built on E-ink technology that can display colors.

Whatever went wrong 10 years ago when tablet PCs were introduced for the first time by Microsoft's Bill Gates has been forgotten. The same PC manufacturers that quickly dropped tablets from their product range, are back again. This time, the Apple iPad has convinced the tech world that tablets are the real thing and practically every manufacturer will want to introduce an Android or Windows-based tablet of its own. Here's the HP Slate 500 Tablet PC.
