RAM (operating memory) has been expanded to 64 megabytes, with most of it available for applications. This is over 10 times more than in 9210/9210i!
This is where the power of the new Communicator comes from. The 9500 will offer over 80 MB of internal storage space - over 20 times more than 9210 and 5 times more than 9210i.
For compatibility with older software, the keyboard also offers traditional arrow keys and the Enter key.
This is a huge improvement and it provides comfortable navigation and control, not only in the built in WWW browser but also in all other applications.
The 9210's four-way navigation key has been replaced with 9-way rocker key (8 directions + OK/Enter).
You will always know that the key has been correctly pressed because you can feel that without having to check the screen or listening to the "beep".
The PDA part offers the usual full QWERTY keyboard. It depends on your personal preferences, but for me the new keyboard is a huge step forward over the 9210 keyboard.
Phone keypad is a separate element and it seems that exchangable phone covers may also contain keypads of different shapes and layouts.
The screen is covered by an anti-reflective layer - one can hardly notice any difference in quality even in direct sunlight.
As opposed to the 9210, the phone screen of the 9500 is now 16-bit color TFT matrix (128 x 128 pixels).
