I had one of these. Sold it for a palm III later on. Then I bought a Newton 2000 upgraded to a 2100. I have that still. For awhile I used that as inspiration for our product designs.
In my collection of stuff it's my pride and joy.
iOS 6 maps aren't released yet. Its in beta and they have 4-5 months to get it all taken care of. Now Apple's maps does have one thing over Googles - its easier to read because its not so chock full of info. Apple's map also has the same info - but you have to zoom in more. I filed a bug report on this asking for more detail at lower zooms. Have you? If you are a developer you would do that.
