After using it for 2 weeks. This is by far the best mobile phone I have used. It has better sound quality and better signal sensitivity than any previous Nokia or Motorola that I have used. I have tried phones that would not work where I live due to the low signal strgength. Unlike most smart phones the E62 really works as a phone. The speaker phone function has great quality for both sides of the conversationAs a PDA, it works very well. It takes a little practice moving from a Palm to not have a touch screen but unlike a Palm it can be fully operated with one hand. Used as a thumb board, the keyboard is very fast. It has tools to both read and edit most MS Office documents. These are only limited by available memory. Using the headset or speaker phone, you can easily look up dates, contacts and other details while using the phone.I have seen the criticisim that applications are slow to start. Compared to Palm, this is true. Compared to MS based devices I have seen it is not. The big difference from Palm is that you only need to start the applications once after powering on. After they have been started, you can switch between them quite easily. Even better, when you come back to an application, you are exactly at the point from which you left, just like switching windows on a PC.It also works great as an MP3 player. The built in speakers are truly amazing. The video playback is not as impressive because Nokia does not support a video resolution that properly fills the screen. I recommend using a tool like Super. It will create much better 3GP than Nokia PC Suite. On the flip side playing a 2 hour movie compressed to 135MB of 3GP using the built in speakers and doing PC synch and file transfers only takes out the top one of the five bars of battery strength. So it is certainly practical to use the E62 as a media player as well as a phone and a PDA. It is a shame that Mini SD cards do not come any bigger than 2GB.Battery life seems reasonable. I am getting three plus days of my normal use on a charge. This week after four full days of normal use it still had enogh battery power left to play a 90 minute movie. My previous Nokia 6200 and Palm M500 typically lasted 2 to 3 days each per charge. Therefore, slightly improved battery life from my previous dedicated units but only one device to charge and carry around.My only real complaints are that meetings entered on the unit default to 'private' instead of public. Annoying to take the time to change if you work in a team with shared calendars. The other is the Sheet application in the built in 'Office Suite'. It is fine for viewing Excel spreadsheets but if you are building them on the Nokia it is extremely annoying. There is a three step process (quick) to unlock a cell before you write into it. If you are creating documents on the mobile, buy QuickOffice for S60 when they get a compatible version.Nokia should take a hint from Sony-Erricson and host a software download site. When I could not find games for specifically for the Nokia, my son suggested that I try the Sony-Erricson site since those phones also use the Symbian OS. I did find several games that are compatible with the Nokia E62 keyboard.Overall, this is a great multifunction device.
