You might have read my review of the N97 – I didn’t like it. Sure, it has a touchscreen and full QWERTY keyboard, but at the end of the day they were both relatively useless – ok that’s unfair, the touchscreen was useless.
But not so with the N900. I’m at CTIA and got a hands on with the device. The OS build still wasn’t finished so a few things were a bit jittery and slow, but for the most part I’m really digging the Maemo OS. It’s much slicker and has a Web 2.0 feel to it, unlike Symbian. The UI is intuitive and for those of you that are looking for a multitasking operating system with an iPhone like skin here it is. The N900 uses a resistive touchscreen, so don’t expect multigesture controls, but you you can zoom in by drawing circles on the screen and flick through contacts, though it still isn’t quite as reactive as the highly touted iPhone. Checkout the video walk through (there’s 2 of them, ones a bit out of focus). It’s a bit long and drawn out, but it should provide you with a good sense of what the N900 has to offer.
