The Sharp W-ZERO3 ES (also know as Willcom WS007SH) looks just like a standard phone with numeric keypad while it still has the side-sliding QWERTY keyboard. With its 2.8-inch VGA screen and 416MHz Intel PXA270 processor, the device has some notable advantages over the T-Mobile MDA, which has similar design and features. Like its predecessor, the W-ZERO3, it features 64MB of SDRAM memory, 128MB flash with 60MB of them allocated to the user, and miniSD memory expansion slot. Other noteworthy features include a 1.3-megapixel camera and USB support.
The handset measures only 5.3 x 2.2 x 0.8 inches (135 x 56 x 21 mm) and weighs 6.17 oz (175 grams). The major drawback of the W-ZERO3 ES is that it lacks Bluetooth and Wi-Fi, which are particularly useful for Pockets PCs.
