Perusing through the mobile phone related website appolicious.com, I came across an article by Kevin Maney stating what he believes will be the top five key developments in the mobile phone world for 2011.  Here they are:

• The primary US mobile phone platform will be divided between Google Android and Apple iOS. I completely agree with this; Android sales continue to rise both in the US and in the UK; although we should probably note that on a world-wide scale, Nokia’s Symbian is still number one.
• Tablet sales will trickle and then explode. Basically, Apple has depended upon the novelty factor to get its sales to where they are and now the new is wearing off. As a gadget, the tablet is currently too expensive for what it offers. So, for tablets to really catch on, they will have to become 1) better and 2) cheaper.
• Lots more apps; lots more almost completely useless apps. According to Mr Maney (and he’s right), when looking through Apple’s nearly 350,000 apps and Android’s 150,000 apps what you find are a handful of good applications followed by a plethora of copycat apps.
• Private location sharing will become popular. While location apps like Foursquare are growing in popularity, there are still plenty of folk who prefer not to advertise their whereabouts to everyone. However, displaying their location to a select few is a different story. Already private location sharing apps (like Neer) are beginning to appear.
• No matter which mobile devices we are using, there will be one common charger. Ironically, while this may seem the most mundane of the 2011 development, I consider this one the best!
