A guide to handheld operating systems
Published: 10 Aug 2006
Palm
Palm OS is currently in a state of flux. Its developer, PalmSource, was acquired last year by Japanese software maker Access, after spinning off from Palm a year earlier. Palm OS 6, code-named Cobalt, has been dead in the water since 2003 with not a single manufacturer -- Palm itself included -- releasing a device with the updated OS. All of Palm's latest models run a variant of Palm OS 5 (version 5.4, in most cases), which is now more than three years old. Fortunately, however, what was good then is good now. Save for a few multimedia shortcomings, Palm OS remains a solid operating system.
Ease of use
Simplicity has always been a hallmark of Palm OS. Although version 5.4 packs more features than ever, it's arguably just as easy to operate as the first version. To run a program, tap its icon. To enter data, write on-screen using the character-recognition software or tap-type on the virtual keyboard. Everything about the operating system seems logical, intuitive and uncomplicated.
We particularly admire the way Palm OS manages applications. You never have to 'exit' a program the way you do on a PC -- you just switch to a different one. And unlike some operating systems (yes, we're looking at you, Windows Mobile), the Palm OS never gets bogged down by multiple memory-hogging applications running simultaneously.
Core applications
Already solid when they debuted back in 1996, Palm OS's core applications have only improved over the years. For instance, you can now attach a photo to a contact -- a particularly nice feature for camera-equipped models such as the Palm Treo 650. The Tasks applet has added new buttons for quick sorting by date and category and lets you assign alarms to your tasks. In short, Palm's core applications continue to combine power and simplicity, and we still rank them top among handhelds.
Desktop compatibility
Palm OS handhelds offer two desktop-synchronisation options: Outlook and Palm Desktop. The latter is a fairly robust information manager that has the advantage of being much more user-friendly than Outlook. It also supplies the tools you need to copy photos and videos to your device, install new programs, and set up your email.
Office compatibility
Although it's not an inherent part of the Palm OS, DataViz's Documents To Go comes standard on nearly every Palm handheld (the sole exception being the entry-level £77 Palm Z22) -- so we'd be remiss if we didn't consider it. The program automatically syncs Word, Excel and PowerPoint documents between your Palm and your PC while keeping them in their native formats (meaning you can also instantly view documents received as email attachments -- no conversion required). You can edit Word documents and Excel spreadsheets and compose new ones, but PowerPoint files are read-only. The software also supports PDFs.
Email
Palm's VersaMail program has the enviable ability to fetch email over a variety of connections: Bluetooth, Wi-Fi or even desktop synchronisation, the latter relying on your PC's Internet connection for mail commerce. The applet itself is solid, supporting multiple POP3 and IMAP accounts, embedded images and virtual private network (VPN) connections.
Multimedia
Although most Palm handhelds offer high-resolution screens and digital audio capabilities, Palm OS isn't the multimedia powerhouse it could be. For instance, you need third-party software (NormSoft's Pocket Tunes Deluxe) to play DRM-protected songs -- the kind you get from online music and subscription services. Palm bundles Pocket Tunes with some models, but the DRM-capable Deluxe version will cost you extra.
As for movies, Palm's Media applet can play them, but only MPEG-1 clips converted by Palm Desktop. For anything else, you'll need third-party software. In fact, to watch a DVD, you'll need two programs: a desktop converter and a handheld viewer. And if you want to play TV shows recorded on a Media Center or TiVo -- something Windows Mobile devices can do fairly easily -- you're pretty much out of luck.
Third-party applications
In terms of sheer volume, Palm OS continues to have an edge when it comes to third-party software. Users can draw from more than 20,000 applications to extend the functionality of their handhelds -- a number still unmatched by the Windows Mobile platform, although this is steadily changing. This isn't to say that software available for the Palm platform is better, only that there's more of it. And more software means more potential functionality.
