It's hard to be all-techno or all-retro on this subject. Myself, I'm drooling over the possibility of a cool third-party (Garmin? Magellan? Tom Tom?) GPS system in or on the dash.
However, I'd just as soon do without power windows and power locks. They are not a convenience, they are just something that can be expensive when they break.
If the GPS breaks, I can just close the lid and pretend that I don't have one...
