I honestly thing that Atom is working (and going to keep working) because we power users are a minority, and for 90% of the people an Atom is enough, perhaps barely enough, but still it can do what the normal user needs, for hardware enthusiast is Almost a blasphemy to buy a processor this weak that (to make everything worst) comes coupled with an old old, not optimized, chipset.
For us a ultraportable laptop is barely enough for the kind of responsiveness and performance we NEED in a machine of our own, but then again, we are a minority and let´s face it, Intel is only giving people what they want, let's just hope it doesn't become another Nintendo and almost forget us.
