Apple's iPhone is one of the most popular smartphones in the world. The iPhone was first introduced in 2007 and is widely credited with bringing effective touchscreen technology to the mass market. However, it was not the first touchscreen smartphone.

Apple has released an iPhone every year since 2007. The company began with the original iPhone in 2007, which initially only launched in the US and was a non-3G phone. Apple introduced the iPhone as a combination of three devices: a widescreen iPod with touch controls, a mobile phone and an Internet communicator. The original iPhone initially received negative press as it had a non-removable battery, no expandable memory and was exclusively sold through US carrier AT&T.

The iPhone 3G was launched in various other worldwide markets a year later and added 3G connectivity, while the iPhone 3GS (2009) kept the same design but added a faster processor and a built-in compass.

The iPhone 4 (2010) saw a completely new design, with the antenna built into the edges of the phone and a sheet of glass on the back. The design caused some controversy when it was discovered that holding the phone in a certain position affected reception quality. Apple offered a free case to buyers that helped solve the issue.

The current iPhone 4S (2011) features an identical design to the iPhone 4 but has a faster processor, more memory and an upgraded camera.

Traditionally, Apple releases one iPhone every calendar year. The releases are timed so that previous iPhone owners who signed a two year contract can upgrade to the new and latest iPhone.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
