Nokia has released two very similar Symbian business-oriented smartphones recently, the QWERTY keyboard-packing E71 and this slim slider. The phones have very similar specs – they both run on Symbian 9.2 OS, both have the same 3.2 megapixel camera, Wi-Fi and A-GPS, virtually the same on-screen...

It's been a while since mobile phones became an essential business tool and a huge number of devices are being specially designed for the purpose (not even mentioning the camera-free versions of some handsets). Nokia Eseries is almost a default name that comes to mind.

Boasting the same features as the E71 minus the QWERTY keyboard, Nokia's E66 is aimed at users who aren't hell-bent on large amounts of text entry. This stylish E-Series handset has the same internal characteristics as its big brother in a smaller, more pocketable form factor.

Questionable build quality of slider; native menu isn't as visually appealing as competing models

Like the E71, Nokia's E66 feels well made, but there are significant differences between the two handsets. The E66 doesn't have the same QWERTY keyboard that sits under the E71's screen, preferring to use a sliding numeric keypad instead.

If you don't consider a QWERTY keyboard a necessity, then the E66 is one of the best smartphones on the market.

Smaller battery compared to E71; Accelerometer can be a nuisance

While we like the E71 better, the E66 is a great smartphone with class leading features. If you want the functionality of a business phone without the bulk of a PDA form factor, the E66 is the phone you've been looking for.
