One of the best combinations of design and function in a smartphone we've seen for some time.

Not everyone is sold on Windows Mobile Professional, but if you're a fan, then Samsung's latest QWERTY phone is worth a look. We size up the Samsung i780 with Blackberry's Bold to see how they fair.

The 6820 is Nokia's business phone. Its previous incarnation -- the 6800 -- was heavily criticised for not offering tri-band or Bluetooth; both of which have now been remedied. For something the size of a regular phone, we can applaud Nokia for shoe-horning a full Qwerty keyboard in.

Data input is one of the biggest issues many people have with PDAs, and while stylus handwriting recognition and Graffiti dont take long to learn, they can be difficult to master, and cant compare to typing on a keyboard.

A capable and beautifully designed smartphone, but weaker battery life means it can’t match the E71

HTC's new Blackberry killer arrives on our desk, and it's every bit the showoff we thought it would be - and that's mean as a compliment.

Wider than a normal phone and encroaching on PDA girth turf, the BlackBerry 7100v is both a capable phone and a capable PDA.

No high-speed internet or bells and whistles, but an easy-to-use and pocketable email phone nonetheless

Plenty of modern phones support email, of course, but what always made BlackBerry special was its push technology. With this, you don't need to dial up to collect your email: just sit back and wait for the messages to come to you. Wherever you are, if an urgent email comes through to any of your email addresses -- and the 7100v supports up to 10 -- you can act on it instantly.

It's not for meetings, it's for meeting up. If you don't like the bulk of a Treo, here's your smartphone.

A good range of business features are slightly let down by the form factor.

You've seen our First Look at the E71, now here's the full review. A stunning phone perfectly molded to the needs of anyone whose life revolves around email

It won’t win any awards in the looks department – it’s rather bulky and large for a phone - but looks aren’t everything in the mobile phone industry, unless you’re Apple.

Packed with features, but too bulky and expensive to compete.

The Sony PEG-NV70X Clie marks a welcome shift in the PDA landscape from the Pocket PC, with a few firsts up its sleeves.

A relatively lightweight Windows Mobile phone with most of the bells and whistles, but not the outlandish $1,000 price tag.

A phone with a personality crisis, but although it’s no iPhone it makes an interesting choice for business users

Slim and well connected, but ease-of-use issues limit its appeal.

Fantastically engineered, but a bit too bulky for comfort.

A little large and lacking in superfast data connectivity, but unrivalled as an email tool.
