I had an N900 when it came out, after falling in love with the N810, one of my favorite devices to this day, I'd buy a new one with modern guts in a heartbeat. The N900 was junk. The build quality was terrible and the software was half baked. Right after it released Nokia said they were cancelling everything about it and pretended to care about software going forward but didn't. In the VERY short time I had one I had the ear piece speaker break (common), the magnets fall out (also common), the screen slide break (also common!), and even when it worked the slide felt janky and the OS was extremely slow. They never fixed MMS, despite promises.
