Not just the processor speed, but RAM as well. I use cable Internet at home and even so it still takes a couple minutes to load a flash page sometimes. It would take forever to download, never mind whether or not the device could even play it. Of course, wireless connections aren't the only way PDA users can update their devices. They can download Flash files and install them into the PDA during their next desktop to PDA sync.
Users can also install files by synching while connected to the Internet.
To accompany the player, Macromedia also released the Macromedia Flash Player for Pocket PC Developer's Authoring Kit . Current Flash developers will find it easy to create files for the mini screens. Even those who currently use Flash 5 can create these files in the newer version and then switch to the authoring kit for conversion. Authoring guidelines and examples are available for downloading along with the kit. Load the Flash 4 Pocket PC development kit.
