It's been a longtime since Palm has released a mobile device that wasn't a smartphone. So although the $300 Palm TX is Palm's top-of-the-line handheld, it is close to three years old.

The Palm Z22, which is of the same vintage as the Palm TX, is an entry-level model. It sells for $99 by itself.

The Palm TX offers Bluetooth, Wi-Fi (802.11b), 128 MB of memory, and a 312 MHz CPU. It measures 4.7 x 3.1 x 0.6 inches and weighs 5.25 ounces. The handheld's 65,000 color screen runs at a 320 x 480 pixels. A flip cover protects the display, an SD slot allows you to increase storage, and there's a 3.5mm Stereo jack for listening to music.

At 2.7 x 4.06 x 0.6 inches and 3 ounces, the Palm Z22 is a compact and light organizer built for the mass market. The entry-level PDA's display runs at a very low 160 x 160 pixels. It has 32MB of memory with only 20MB of that actually available to the user.

Additional features include Palm OS Garnet 5.4 like the Palm TX and a 200 MHz processor. There's no memory slot to add more storage via an expansion card.
