Arriving right on schedule, palmOne officially introduced the Tungsten T5 just a few minutes ago. Completely skipping over the T4, their new flagship PDA has a massive 256MB of storage, a 320x480 pixel LCD screen, a 416MHz processor, and built-in Bluetooth. The big disappointment: it runs on Palm OS Garnet 5.4, not Palm OS 6 (aka Cobalt) like a lot of people had predicted/hoped. The even bigger disappointment: no built-in WiFi (we know, it's totally weak). Should go on sale November 3rd and retail for $399, but you know that by that point it's gonna be completely overshadowed by the Treo 650 announcement scheduled for the week before.
