Why? What task requires dual core for in your mobile device? Do you feel that your N900 is underpowered? What processing features do you miss on your N900? I am a technomaniac, and I do have an urge to go with the latest n' the greatest, but the thing is that the `greatest` after owning an N900 will never be the same. I really cannot force myself back to ye oldie smart phone, let alone feature phone platform, and there isn't anything on the market even remotely close to what the N900 gives. It replaced my laptop almost completely, and there is no pocketable device in sight that can replace the N900. What use is a dual core, 1GB of RAM, super-fast GPU or 64GB of storage when you really cannot tap into it and have to rely on manufacturer's/carrier's good will to let you use the device you've already paid for?
