Happy with my hero - I like the gmail client, like how it takes pictures from faecbook for my contacts and my google calendar pops up event reminders on the phone too - guess that should be expected.
GPS is very good with google maps - just need to have signal like everything else. I did hear someone say iPhone did better with locating via hotspots / masts. As even the iPhone was 2 streets out I guess you didn't have a GPS lock on either phone.
Not seen any clear blue water between it and iPhone's I've tried to be honest, quite keen to try and iPad when they come out here though - think I could get on with the format. If iPhone was a little more reasonable in price I would probably have looked at one instead as the market leader is usually better supported - but it wasn't worth the extra cash for stuff I'm not really all that interested in.
