The Touch Diamond packs in a lot of features and is a good effort by HTC to rival the iPhone's touchscreen usability while retaining the power and extensibility of Windows Mobile. But despite the hype, the Diamond is distinctly half-baked. Granted, the Touchflo 3D works better than ever to turn Windows Mobile into a genuine phone interface. It hides the ugly-duckling Windows interface away successfully, and browsing the web on HTC's version of Opera Mobile is fantastic. But as a complete package, the Touch Diamond just doesn't convince. Not only does the build not reach the standard set by the iPhone or even the previous generation of HTC Touch phones (this is especially disappointing given the £400+ price tag), but the performance is laboured and the software not entirely stable.
