This is not like the slider on the palmOne Tungsten T3, but rather a set of controls that slides out from underneath the display. It has a 480-by-320-pixel display, 3.8" diagonal; Palm Garnet (OS 5.2.1 Japanese version); 128 MHz Sony Handheld Engine 64 MB of RAM, 40 MB available to the user; 128 MB of ROM, 95 MB available to the user; Compact Flash II Slot (handles both memory cards and peripherals); Sony Memory Stick PRO slot; and built-in Wi-Fi (no Bluetooth).
