After you turn on the Nokia 7710 it displays the main desktop with many icons of the integrated and later installed items. The user can easily modify the desktop item's layout: put them on the desktop wherever he wants. The icons need not to stand only for applications; it is possible to assign a shortcut to any file. To avoid the chaos on the desktop, the user can sort icons to various groups and use them for filtering of the display. There are many icons - 44 in my case and I installed just a few programs.
Nokia 7710 supports graphic themes, so called Motifs, which allows you to change a look of the user interface. In the phone that I have available there are two themes and I am sure that others will appear on the Internet. Moreover, Nokia released a Theme Studio tool, which can be used for creating customized graphics.
Series 90 display consists of several sections:
It is good that individual bars can be mostly manually switched off and in some application you can even activate a full screen mode. So the application's desktop can have several resolutions:
You can select a size of the font and graphic objects in three levels for most of the programs. You do not have to go to the menu; one of the keys on the right side can do it. Each application remembers its own setting. I personally prefer the most detailed view, where the font is really extremely small.
Even that hardware keys can control smartphone's basic functions, you cannot do without the stylus. The latter is necessary every time when you need to enter characters, it is also necessary to tap on various icons and other items. For example, only the stylus can control buttons in the command bar.
It is impossible to connect a Bluetooth keypad; you have to choose from two methods of typing.
The first one is a keypad on the display: when you tap to a text field it displays a drawn keypad - either small or big, it depends on the setting. With the stylus you peck on the letters and put the words together. If you choose the big keypad, it is possible to press the keys by fingers. It could be better: the fingers control would have been very comfortable if the keypad can be stretched over the whole display.
In addition, you can use handwriting recognition: when you tap on a text field, it displays a small frame, where you can write with the pen. Identification is reliable but if a person has a specific handwriting it is possible to learn the smartphone for each letter individually. The frame with the software keypad and with a block for entering the characters can be moved anywhere on the display.
From the two methods of writing I used more the second one. The identification method is very reliable; moreover, it is not necessary to wait for representation of every letter. Just write the characters fast one by one and the smartphone will fold them up then. It is sure that you have to be in standstill during writing or typing; it doesn't work by walking. This is what makes the 7710 a bit unpractical.
Contrary to other touchscreen systems, it differs by way of taping the stylus on the icons. Single tap is the same but a double tap works like with the old Psions. It doesn't matter on the time duration between two taps. You can tap once and for the second time in five minutes if you want; fast double-tap is not necessary.
Series 90 supports work with clipboard - it is possible to copy, cut and paste items. The clipboard is controlled from the menu.
Running applications cannot be closed in a standard way. There is an applications manager that can do it, but you have to shift to the manager first. The system doesn't mind that programs remain open; it will close them by itself when more memory is needed.
