I have Lumia 800 and N9. Lumia 800 is the European version, so I dont get the benefits of 3g on the ATT or T-mobile, and N9, of course, works well on both. Lumia 800 is way smoother and more pleaseant user experience. There is no stuttering, lagging, and general feeling that you are being waterboarded. Lumia 800 has the greatest email I have seen on the touchphone, and since I use email a LOT, I love it. N9 email plainly sucks. It doesnt save my drafts if for some reason I move away from the email, and the whole multitasking is a myth. Nothing happens in the background of N9. A myth. and that 1Gb of RAM is wasted on N9. I have no desire to get L900 as L800 is pretty much the same and I like its form factor, but I can see how few of the individuals above are having a good time with it.
