Yeah, I saw the Wireless Internet as an option/accessory for the X3 as well, not completely new in the 1er.
The 1er does have slightly more usable cargo space and rear seat room when I sat it in at the dealership. Like I said, I'd have to drive one to make final judgments but at least in appearances it does appear to be much better. Then again, I like the Astra and Golf a lot as well. Clearly, spoiled for choice in Europe when it comes to frugal and fun hatchbacks.
