its bloated, slow, can lock up your data forever if you dont know what your doing, has features no normal person wouldnt need, lacks features enthusiests want, put a "security blanket" of encryption and lock down for the warm and fuzzies of people who dont know what a computer is, has a play skool interface.

if they rolled out a patch/SP that changed the NTFS partition limits, or at least allowed GPD disks, XP pro would be perfect in my opinion.
