It's a wireless world, and what better way to explore it than with a mobile phone handset? Year by year, networks get faster and processing power fits into smaller spaces, so it's no surprise that devices such as the iPhone and the Blackberry are proving popular ways to stay online.

When it comes to ease of use, the iPhone currently has little competition for most users who need an effective tool to make calls and access the web without tech hassle. With consumers demanding ease of use and reliability, we'll be following the launch of the next mobile-computing contenders, using the eagerly awaited Android mobile operating system. We'll be testing Google-equipped handsets as they appear, and who knows - Google may be able to win hearts and minds with a usable web surfer where Microsoft, and to a lesser extent, RIM and Symbian have largely failed. You can read our first look at the T-Mobile HTC G1.

It's been seven years since the first iPod was launched to an unsuspecting world. Apple has now tallied up sales figures of over 160 million - and a 73 percent market share. Over that time, capacities have gone from 5GB up to 160GB... and then down again. In the case of the fourth-generation iPod nano reviewed this month, the maximum capacity is 16GB.

The reason for the reduced storage is the increased use of flash memory. That, and the realisation by most people that you don't really need to carry 40,000 songs in your pocket every day, other than for bragging rights. With no spinning disks, the flash storage medium won't get messed up when you take your music for a run.

Extra capacity can be useful, especially when you introduce space-hungry video into the equation. Many users, then, will be thrilled to see the introduction of half a terabyte of storage in a 2.5in hard disk. Too big for an iPod, maybe, but look out for portable USB drives of this magnitude, priced within reach from £99. We've reviewed three USB models this issue: Verbatim's Portable Hard Drive USB 500GB; Fujitsu's HandyDrive-IV 500; and Amacom's ezSecure.

But the market will continue to move on. By this time next year, perhaps we'll be scoffing at the thought of a mere 500GB capacity, and in something as clunky as a 2.5in laptop drive.
