Googles first own-brand mobile phone is undoubtedly a superb piece of engineering. Ergonomically, it just slips naturally into the hand with its all-round soft curves rather than the hard edges of, say the Motorola Milestone. At 130g the Nexus One is lighter than an iPhone (136g) and Milestone (170g) as well as being narrower and thinner (at 11.5mm) than these two most striking competitors. It has a fantastic 3.7 inch widescreen, AMOLED display, delivering 720x480 pixels resolution. Arguably crisper and clearer than any other display on the market, it delivers touchscreen responsiveness definitely in the ballpark of the iPhone and, moreover, it is fast. The combination of Android 2.1 sitting above a Snapdragon CPU clocked at 1GHz with 512Mb of RAM and ROM really does enable you to zap through opening up applications and then moving between them. Its multimedia credentials, are quietly competent rather than superb - such as the 5 megapixel, autofocus camera with LED flash and its 32GB memory card capacity. Where the Nexus One really impresses, though, is in what could be called its charisma, if it could walk into a crowded room, heads would most definitely turn. Its Teflon-coated back and sides are simultaneously rubbery and tough yet soft and almost sensuous, a strangely compelling tactile experience.
