Handspring today announced the availability of a software upgrade for the Treo 90 handheld organizer that provides compatibility with Secure Digital Input/Output (SD I/O) expansion cards. SD I/O is a standard that enables the addition of new functionality such as Bluetooth, 802.11, GPS, presentation display or digital imaging to a host device like the Treo 90. Treo 90, a lightweight organizer with a built-in QWERTY keyboard, features a full-color display and 16 MB of memory. The <A HREF="http://www.handspring.com/suppor">upgrade</A> is available free of charge.

There are currently two expansion cards that can take advantage of Treo 90's SD I/O capabilities. One is MARGI System's Presenter-to-Go, which connects the Treo 90 directly to digital LCD projectors or other VGA devices to show business presentations stored on Treo in full color. This solution includes software that allows for slide presentation from any printable Windows application including PowerPoint, Word and HTML.

The other expansion card currently available is the Palm Bluetooth Card. This card lets people wirelessly link a Treo 90 to any other Bluetooth-enabled device within a 30-foot radius. For example, a customer could use the Treo 90 with a Bluetooth-enabled mobile phone to access the Internet, email and messages wirelessly.=20
