This is what Which says about it. Just bought one for my missus.
It scores 65% which is actually high.
If you’re after a mobile handset and only the highest of the highest specification will do,
then the Nokia N73 could be the phone for you. It’s a 3G model simply crammed with just
about every one of the latest mobile technologies available.
It does all the basics rather well too. Sound, reception and battery quality are all above
par and it's easy to use for both calling and texting.
The music player is a bit of a let down in terms of both ease of use and sound quality
but it is complemented by a stereo FM radio with RDS and twenty pre-sets.
The digital camera boasts a massive 3.2Mp of resolution and a Carl Zeiss auto-focus lense.
Not surprisingly it performs rather well in our tests too. You'll get good quality snaps in both
daylight and an office environment. It's only when the lights are dimmed that quality starts
to drop off. A second VGA camera means you can make video calls via the 3G connection.
Of course Bluetooth, infrared and USB connections are all possible and if that wasn’t enough
the N73 is also a smart-phone capable of displaying office and adobe documents. However,
the Symbian OS menu system might not feel as intuitive to use as the regular Nokia systems
and it would have been nice to see a memory card supplied as well as the slot.
Pros: Huge display, array of impressive features, great 3.2Mp camera
Cons: Small keypad, could be a little over-complex for some, no memory card
I've just got the Sony Ericsson K800i Cybershot. Scores 64%. Slightly smaller than the N73.
A bit less

IMO.
Sony Ericsson have blurred the line between phones and music players with the addition of
the powerful Walkman brand name to the mobile handset market. They now look set to do
the same for phones and digital cameras, with the introduction of the excellent Cyber-shot brand.
Reminiscent of the classic K750i but slightly chunkier (it is a 3G model after all) and with a
magnificent looking display, the K800i is all about the camera. And it’s impressive - 3.2Mp
resolution, close-up macro, auto-focus and an easy to use photo editing package.
It takes great shots, even in dim light conditions thanks to the built-in flash, and is intuitive
to use. There's also a one button option to blog your picture onto your own website - truly
joined up thinking from Sony Ericsson.
There's also an FM radio with RDS plus an easy to navigate, built-in music player. We were
impressed with the music player but sound quality with the supplied headphones could be
better and there's no headphone jack adaptor. Bluetooth, USB and Infrared are all included,
as is flight mode.
The basics are all in order too. Reception, call sound quality and battery life are all good.
There’s a memory card slot as well as the 64Mb of internal memory. However, no card is
supplied so you'll have to shell out some extra cash to boost the memory capacity.
Pros: Impressive digital camera, decent music player and radio, great lens cover, memory
card slot, good reception, good call sound quality, good battery life
Cons: Display could be prone to scratching, no memory card supplied, no headphone adaptor
