O2 Atmos

This menu system on the Atmos is fairly straightforward. Without a touch screen, all Windows options have to be navigated via the directional pad and select buttons, which at first seems quite restrictive if you're used to the touch screen of a 'proper' Pocket PC. However, in fact it's more suited to use on the move and you can navigate the OS one handed.

Pressing the Start button brings up the first screen of options, and you just keep pressing one button to scroll through all of them, page by page. The right soft key defaults to your contact button, but when a message comes in via Outlook Mobile is changes to 'Message' so you can go straight in.

The home screen on the Atmos is standard for Windows Mobile. At the very top, next to the signal strength indicator, it display a 'G' for when you're in 3G areas, and an 'E' when your dropped down to Edge. Beneath this you get a list of your most recent apps and you can scroll left and right through these.

Underneath this you it displays the network, the state of your Wi-Fi and the date and time, as well as the number of unread text messages and emails you may have and you can go into any these options by selecting them.

One of the great things about the Windows smartphone platform is the wide range of applications that are available. However, one of the most useful is pre-installed - Windows Live Messenger. The presence of the keyboard, and an unlimited data plan, makes the Atmos ideally suited to this kind of use, and I was soon typing, "I'm on the train!" to those in the office.

In all seriousness, it's a useful tool for staying in touch. Indeed, when I lost connectivity to the Messenger service on my desktop, it proved to a very useful backup.

Skype installed on the device without issue and for the most part works well. However, one problem is that Windows Mobile doesn't give it access to the phone speaker to third-party apps, with the result that your caller's voice only comes out on the main speaker, which causes echo issues and isn't exactly private. You can get round this though by using the supplied clip on headphone/mic remote and on one occasion it caused the phone to restart.

The headphone attachment attaches via standard mini USB at the base, and does a good job whether you want to keep track of industry pod casts, or just enjoy your own personal music choice. A mic is built-in so you can take calls without taking off your headphones and it stops playing tracks when a call comes in and resumes neatly when it ends. Best of all, the remote has a standard 3.5mm jack so you can use your own headphones.
