forgot A300, that sucks.
low quality screen, little battery and very unusable keys/joystick keys, also need adaptor to normal headphone connector.
Have only SD slot, for CF need buy addon jaket.
Actually, the A300 is an excellent PDA for the price. It\'s light-weight and REALLY fits in the pocket. It makes a great eBook reader, dictionary and with a program like TimeSleuth, it\'s great for time tracking. Battery life is quite good, the screen, while it\'s not like the CG Silicon screens on the more expensive models, is brighter than most other PDAs. I have been using the SL-A300 every day since it was released in August 2002 and have no regrets. It makes a great companion for one of the bulkier models like the SL-C860.
In short, I highly recommend the SL-A300.
