Five touchscreen-only smartphones

Even though many times a keypad will be added to a smartphone to make it easier to use, having one with a touchscreen as the main means of interface also has its advantages. The primary one is this: The bulk is reduced, allowing for a more compact device. If you like them keyless, here are five smartphones without numeric or QWERTY keypads.

	1.	Apple iPhone 3G       CNET Asia rating: 8.3 out of 10 The good: Offers critical new features including support for high-speed 3G networks, third-party applications, and expanded email; improved call quality is improved; continues to deliver an excellent music and video experience. The bad: Continues to lack some basic features that are available on even the simplest cell phone; also, we prefer the original iPhone's design. The bottom line: The iPhone 3G delivers on its promises by adding critical features and sharper performance. The iTunes App Store is pretty amazing, and the 3G support is more than welcome. We still have a few gripes, but the iPhone 3G is a big improvement over the original model. Review | See full specs | Rate this
	2.	HTC Touch Diamond2       CNET Asia rating: 8 out of 10 The good: Sharp 3.2-inch WVGA display; enhanced TouchFlo 3D interface, fast Internet browser; text input comes with haptic feedback; stylish design. The bad: No 3.5mm audio jack; relatively expensive; no bundled turn-by-turn GPS software. The bottom line: HTC has dug deep into Microsoft's underlying OS interface and made tweaks that allow for a great user experience on the Diamond2. Review | See full specs | Rate this
	3.	Samsung Omnia SGH-i900 (8GB)   CNET Asia rating: 8 out of 10 The good: Full range of wireless features; haptic feedback; improved text input methods; navigation software included; attractive design; excellent battery life; Opera 9.5 browser included. The bad: Some apps may not work properly; finger scrolling not consistently implemented; use of microSD slot requires battery removal; no stylus slot. The bottom line: The Omnia is a good alternative to the HTC Touch Diamond with a competitive price and a truckload of features, though Samsung does need to work on the interface to improve its consistency and usefulness.

	4.	Nokia 5800 XpressMusic   CNET Asia rating: 8.1 out of 10 The good: Good set of connectivity features; unlimited music download with Comes With Music; hard-to-match price for features. The bad: Inconsistent user interface; not many apps optimized for the screen resolution and touch UI. The bottom line: Nokia's first outing with the S60 5th Edition platform and unlimited music download service proves to be very compelling. It just needs to address the inconsistencies in the user interface. Review | See full specs | Rate this
	5.	HTC Touch HD   CNET Asia rating: 8.3 out of 10 The good: Huge 3.8-inch WVGA display; 3.5mm audio jack; improvements made to TouchFLO 3D; 5-megapixel camera; nice design. The bad: Lacks a directional pad; short battery life; no LED for camera; orientation sensor doesn't work in some applications. The bottom line: While it probably won't strike a chord with the average iPhone user, the Touch HD is a great effort from HTC, demonstrating that it can still put more into its already formidable range of high-end handsets.
