Design
The Treo 650 is primarily made of plastic but has a overall solid feel. The front of the device houses the status LED, earpiece speaker, screen and the keyboard. Unlike previous palmOne handhelds, the status LED on the Treo 650 is quite functional and can indicate a number of different states as shown here. The edges and corners of the device are all smooth and slightly rounded. Below the display lies the central navigation ares with the application buttons and the 5-way navigator. The full qwerty thumboard lies below the screen completing the data centric smartphone design.

Hardware
The 650 is powered by a 312 MHz Intel PXA270 processor and runs Palm OS Garnet v5.4.5. It has 32 Megabytes of non-volatile memory, of which 23.7MB is user accessible. The non-volatile memory allows the memory contents to be preserved even when the battery is removed or out of power. The Treo also incorporates a SD memory expansion slot which can accommodate MMC, SD and SDIO memory cards. However, it does not yet support the palmOne WiFi SD card at launch. palmOne claims to be evaluating the situation, so there is only a slight potential the card will eventually be supported.

Display
The Treo 650 has a very sharp 16bit color, 320x320 pixel TFT screen, which measures just under 2 x 2 inches. palmOne outfitted the 650 with a high resolution screen in about the same spacial area as the Treo 600 making for a very crisp text and graphics experience. The fonts are extra smooth and photos and graphics look great. The screen also offers improved visibility in direct sunlight, though slightly washes out. There is a backlight slider which can also turn the backlight completely off.

Camera
The Treo 650 has a built in VGA camera with 640x480 (0.3 megapixel) resolution and automatic light balancing. It has 2x digital zoom and can also capture movie clips in the .3gp format. The camera's quality is vastly improved over the Treo 600's. Photo's are more realistic and colors and light balancing are much more accurate. Pictures can be automatically stored in configurable photo albums to either the handheld memory or preferably an SD card.

Bluetooth
In addition to its wireless phone network capabilities the Treo 650 has built in Bluetooth wireless. Bluetooth enables a number of new accessories including wireless headsets, bluetooth GPS, wireless hotsyncing etc. When enabled, with Bluetooth Dial up networking can use your Treo as a mobile modem taking advantage of its data connection to use on your laptop or PC.

Battery
The Treo 650 comes with a 1900 mAH Li-ion rechargeable battery that can be removed via a cover on the back. Additional replacement batteries are sold by palmOne for $59.99 USD each. Battery life for GSM models is rated at 6 hours talk and 300 hours standby, while the CDMA version gets 5 hours of talk and 300 standby. Tapping on the small battery icon will tell you how much battery life is left percentage wise. With my own personal usage pattern, which included heavy internet usage and a few phone calls a day, I am able to charge up every 3-4 days or so, which is very impressive for a high end phone.
