Google Maps for iOS is a usability nightmare. It looks cool but it's a real PITA.
I think Google uses iOS as a testing ground for new design ideas to see how well they catch on before bringing them to Android. If they think this design is good they'll probably bring it to Key Lime Pie. I just hope they don't make Maps on Android anything like it is on iOS, or if they do, I hope they fix it first.
Im curious to hear your input on Google Maps on iOS, like what problems you've seen. Also what do you think is the best maps software? I use Google Maps plenty and I just type the destination and hit navigate. Works without a hitch. But I do have to say...it did make me drive in a circle for a bit for no reason.
