multimedia functions may not be as good as the Nseries, the Eseries is more business oriented. However, its not too bad in that department.
Camera - 6/10 (reason being is if you tweak the settings the pictures are decent. we're talking bright environments here, low-light is bad as with other cameraphones, with some like the N82 being an exception)
Music - 7/10 (sound quality is nice with a 2.5 to 3.5mm headphone adapter, you can tweak the sound with the equalizer, has playlist options, easy to search for music, etc)
Video - havent played any, so I cant say, but the screen is small for video playback
Gaming - 5/10 (there are some very nice games out there, but some games may not look good due to screen size and res. You can modufy your phone to install ngage games, but i dont really game much on my phone. Also, the E71 lacks hardware acceleration so graphics arent that pretty compared to the high-end Nseries phones.
I normally like multimedia oriented phones, but I value the calender, internet and certain features more, so I decided to get teh Eseries, as far as gaming goes I would be happy with a good laptop, I dont have time to be honest.
I used to have a LG Viewty with a nice 3" touchscreen and the video playback is really good, but I realised that I only play those videos to show my friends who good they are on the phone and not actually watch them.
I do listen to music very very often on the phone and although it cant beat the iphone in this department, i think its sufficient enough for me, just need to get the headphone adapter like i mentioned.
As far as the camera is concerned, i wish it was better, my LG Viewty took nice photos, but I dont use the camera so much, so I can make the sacrifice.
The best thing about this phone is how slim it is, how nice it feels in your hand and how sexy it looks, people keep staring at it

Its also very fast and responsive.
