Anyone who prefer an n900 over a decent modern Android phone for anything other than nostalgic reason is a complete fanboy, maybe even slightly insane.
The n900 is just too slow in almost everything. And I know some of you will argue that if it had quad cores and 2GBs of ram it would be fast too... Well it doesn't.
I was able to load theverge mobile site, scroll down and hit "full site", load that and reload SIX times before the n900 was able to load the full site once, on my iphone 5. And I imagine a modern android phone will be just as fast.
Not to mention the terrible battery life, bad camera, low quality lcd, resistive touch screen and chunkiness.
The world has simply passed the n900 by, sadly. I did love it back in 2009.
