Nokia on Tuesday said it has started shipping the N900, its new flagship. The crossover between its Internet tablets and media smartphones is the company's first phone to use Maemo Linux instead of Symbian and is better-suited to modern computing: it has both a full Mozilla-based browser with Flash but basic multi-touch and multitasking that can support many simultaneous apps open. Helping this is along are a fast ARM Cortex-A8 processor and 256MB of RAM that closely resemble the hardware in the iPhone 3GS.
