On balance having had one for a couple of years (Mio 168 + CoPilot) I wouldn't be without it. Like all tools, needs to be used with intelligence, and like all computers can be totally bloody-minded (insists on taking me straight through the middle of pedestrianised French towns, totally ignoring bypasses). On the other hand it's never thrown a map at me saying "Read it yourself if you're so bloody clever!" :-)
