Internal rechargeable batteries aren't perfect, though. When they run low on juice, you have to charge them. There's no popping in a pair of fresh AAAs and instantly getting full powerif you don't have access to a wall outlet or one of those fancy new fuel cell chargers, you're out of luck. Fortunately, the Edge's phenomenal battery life makes this a non-issue for most users.
What it doesn't have
Handspring isn't the only innovative company churning out Palm-based handhelds, and the competition has raised the bar since Handspring's debut. Unlike some competitors, the Edge lacks a jog dial or any kind of specific scroll wheel. The fact this functionality isn't included in every new handheld computer astounds me. Given that the screens on these devices are so small and capable of showing so little information, something to facilitate easy scrolling would seem to be a no-brainer.
One final little gripe concerns the Edge's buttons. While embossed, and quite easy to use with a finger, they're not concave like other Visor handhelds. The concave buttons on the Visor Deluxe are much easier to tap with the stylus than those found on the Edge.
The operating system
The Edge runs the Palm OS, version 3.5.2H2, which is functionally quite similar to what the vast majority of Palm-based PDAs are running. Handspring does have a few software tricks up its sleeve with the Datebook application, though. These enhancements aren't anything earth-shattering, but they make looking up contacts a little faster and a little easier.
Realistically, we're not going to see a big leap forward in the OS or software for Palm-based handhelds until the second half of 2002. By then, Palm should be ready to introduce a radically different OS based on technology it acquired with its purchase of the Be operating system.
