- GLOBAL - The Nokia E72 is the device so many of you have been waiting for. If nothing else, today's news that the E72 is now in stores will answer the endless requests we've had wanting to know when E72 goes on sale. And we're soooo excited. What a device. It's never easy following up an absolute winner, as the E71 is, but the E72 doesn't disappoint (I had a little play with one last week - it's really lovely). The E72 isn't just about a few tweaks and a nice makeover, it also adds a whole bunch of new features. Read on to find out more.Built on a winning formula, the QWERTY laden E72 takes the best of the E71 and adds more. Brand new is the optical navigation key which makes hopping around the device's menus a delight. New for this version also comes the latest version of Ovi Maps, compass and a five-megapixel camera.The latest version of Nokia Messaging is on board too, giving you access to multiple work and personal email accounts. What's more, Nokia Messaging now supports Instant Messaging too, so you can dial into your favourite IM communities right from the homescreen. Windows Live Messenger, Yahoo! Messenger, Google Talk and Ovi Chat are all supported. And when work gets too much, you can flick to your "play" profile with individual settings putting the E72 into relaxed mode.Nokia today also revealed research highlighting that people rely more on email than traditional phone calls or text messaging when sending and responding to critical information. According to the research, we're spending on average five days a year responding to email, whilst 46 per cent of us choose email over voice or text to send and receive important information. Good thing the E72 is finally here then.Don't forget to share your excitement in the comments below.
