Nokia N900 Necromancy

I remember when the N900 came out other phones including the iPhone could not process a web page with AJAX or most javascript and Flash. It truly gave you a desktop experience on a phone. You could open a terminal and ssh into a server or do whatever you want. Another funny thing people forget: It had another Finnish company's game for it that later became wildly successful: Rovio Angry Birds

Web browsing wasn't a particular strength of it. I remember the N900's browser came with a version of Gecko around a year old by the time. Flash support was a downside. And of course, contemporary iPhones ran circles around it in smoothness.

I think Stellarium got its mobile start on N900 as well.
