Ah, but x != .999, rather x = .999 ... (repeating for ever and ever, or as long as you'd like to count). Refer to my previous post, and click on the link (it explains things to skeptics quite well, I think). And it's not a "theory" -- it's actually quite established that .9 repeating is the same number as 1.
