Especially Sony, also showcasing all kinds of other gadgets like new digital cameras and VAIO notebooks, was swamped by visitors all day. It features Sony's Memory Stick media slot for removable memory, Jog Dial control for navigation, and in its first generation it is supposed to come with digital imaging capabilities. So far, Sony has not announced anything regarding availability and pricing. While Sony, Palm Computing and Handspring base their PDAs on the Palm OS platform, they go different ways when it comes to expansion modules. All this gets pretty confusing for consumers, and of course the different technologies are completely incompatible.
Proprietary standards are never a good idea.
Just image this kind of thing had happened in the PC world. Major PC manufacturers like Compaq, Dell, Gateway and others decided to each use a floppy drive that is incompatible with the drives of other manufacturers. Well, you could not just simply copy a file to a floppy, take it to your friends' house and copy it on his or her machine - unless it is the same brand. If handheld systems, and that also includes cell phones, MP3 players, and similar devices, all used the same expansion standard, it would be possible to share peripherals among them. VIA, the inititator of the PC133 Initiative, are now shipping four 133Mhz chipsets, which benefit users of both Intel and AMD CPU's.
