The SE-300 is a touch-screen PDA, similar to a Palm Pilot. I have had it for a year and a half now, and have found it to be very useful. There are 2 ways to input data, you can write notes in your own handwriting, or you can use the small on-screen keyboard that appears whenever you need it. It has many inbuilt features. A clipboard, used for keeping documents or emails downloaded from your PC, various calenders with alarms, a memo facility (i use it like a notepad ). It comes with a link cable and software for connecting to your PC. The case doesn't feel too robust, but saying that it is still in good condition. The stylus fits neatly into the case. The backlight is good but runs down the batteries. There are also add-ins to be downloaded from the internet, including a game-pack. Unfortunately no extra add-ins have been added to this site since i first visited it. It has other standard features too, address book, a drawing feature, an expenses tracker, calculator, clock etc. The cut and paste facilities will seem fairly intuitive to anyone used to a Windows environment. The unit is very neat and compact, although it doesn't come supplied with any sort of protective case.
