A notable innovation on the software front is Active Notes. This is an application you can use to insert images, sounds, Web addresses and more into ordinary text based notes. It is a nice idea, and could prove useful.
The headset connector is 2.5mm sized and rather boringly Nokia provides a simple one piece headset. Remember, this is primarily a mobile aimed at professionals and Nokia still doesn't realise that many professionals like a bit of music when they are out and about.
This is a shame as the battery life on the E51 is very good. I got thirteen and a half hours of music from a full battery charge. This isn't quite the best I've ever got from an S60 phone, but the E65, whose usability I liked so much, just edged under ten hours.
However, it is the camera that lets this phone down. Its base specification of 2.0-megapixels doesn't inspire confidence at the outset, and in use it was average.
Shooting photos of anything even vaguely moving was a no-no. All my test images of moving subjects were blurred and unsatisfactory. Both indoors and outside the camera had ‘issues'. The coloured dish, photographed under normal household light, looks grainy and insipid. The flowers, photographed outdoors on a dull December day, are way overexposed and their bright and vibrant yellow is completely lost.
If you need two-way video calling or a good camera on your mobile then the E51 isn't for you. But in every other respect I found it to be a great little mobile.
