Well from memory Intel sold off the general purpose ARM CPU division to Marvell back in 2006 or so. Though it kept the ARM chips that were specialised for storage or networking IIRC. So technically Intel has always made ARM chips in one form or another, just not any that slot into a mobile phone.

I really wanna know the logic behind that decision. They probably thought ARM was not worth it? Despite it being used successfully in Pocket PCs?

Based on what another commented has said it seems Intel bought the ARM license from DEC, and given that they sold off only the consumer ARM chips - keeping the task specific ones - it makes sense in a way. It was so they wouldn't have any internal competition or divided focus away from their low power x86 chips - the Atom's.
