The 6.3-inch Galaxy Mega isn't easy to carry around or use one-handed and is short on internal storage. Having said that, it's the obvious handset for anyone who likes Samsung's 'Android-on-steroids' approach and is attracted by the Galaxy Note 3's size, but doesn't need stylus support.
This rugged 10.1-inch Android tablet comes with a decent base specification and has plenty of options and accessories on offer. It's no low-cost tablet, and runs the ageing Android 4.0, but it should appeal to vertical markets that don't require Windows.
The Lumia 1020 has a truly impressive 41-megapixel camera and a high-quality 4.5-inch AMOLED screen, but many Windows Phone fans might do better with the 920 and a good dedicated camera.
If you're an existing iPhone user and weren't tempted by the iPhone 5, then the colourful 5c is worth considering as an upgrade. However, iPhone 5 owners should think carefully: there's very little difference between the core specifications of the two handsets, and iOS 7 is just a download away.
The 2013 Nexus 7 is a sleeker, lighter and better-specified device than last year's model. There's still no Micro-SD card support, but good all-round performance and battery life, plus a competitive price, add up to superb value for money.
This excellent Windows 8 tablet/ultrabook hybrid has a well-designed keyboard docking mechanism, typically solid build quality and a specification well suited to mainstream business use. It has a hefty price tag, though, and the lack of SD-based storage expansion is perplexing.
The Lumia 925 is a slimmer and lighter Windows Phone 8 handset than its 920 predecessor, with a neater and more ergonomic design. It lacks integrated wireless charging but supports LTE and NFC, and has an excellent 4.5in. AMOLED screen.
Although it's well built and delivers decent battery life, the ElitePad 900's combination of a basic Atom-based tablet and a range of optional extras is an expensive way to build a work-ready system.
The 8-inch Galaxy Note 8 is reasonably comfortable to hold one-handed in portrait mode to make jottings with its pressure-sensitive pen, and is a delight to use. Still, you'll need to really want the added features that pen input brings to the device, because it's relatively expensive.
