Major CONS compared to 9500 Communicator

If you are used to a 9500 you will HATE the E90. Loads of things you could do on a 9500 are NOT POSSIBLE on E90. Switch from S60 to S80 means it is no longer Menu based, and Menu key removed, along with cursor keys. So for editing Sheet and Word it is TEDIOUS and so many keystrokes.
Browsing the web is also so slow compared to 9500.
Font sizes are large and fixed. So see fewer email and other folders on screen.
Hardware is nice, but software and what you can to with it as a business user is worse than before. Switch from S80 major mistake.

Even as a phone there is now just one phonebook, you could have multiple before.
D-Button interface is hit and miss, and drives a skilled 9500 users nuts.
Why switch from the usual white screen to a dark blue screen?
Using it in practice is a nightmare, and I have sent mine back for a refund.
This is NOT worthy of the title Communicator.
TRY before you buy it. You may love it, you may HATE it.
If you liked the previous 9300 and 9500 you will rapidly find huge shortcomings and HATE it.
Be warned.
