I just read the quickstart guide and manual for the Rino (no - I haven't received mine yet, but the manuals are available for download). These are the things that sold me on the Rino.
1) I love the ability to show waypoints 'by distance' instead of 'by name' - that allows me to download a bunch of waypoints and then when I get where I'm going, I can see which ones are closest to me. This may be available on other units, but I never saw it.
2) It's also possible to send a waypoint to another Rino user even if you're not at that location. (Meet me here in an hour.)
3) In addition to being able to speficy your name, you can also choose a face icon to represent you. This is displayed on the screens of other Rino's you transmit to.
4) You can tell it to scan only selected FRS channels, or all channels.
5) There are 10 ring tones, plus vibrate mode.
6) You can scramble voice transmissions so only other Rino users can hear you (not other FRS users).
7) Waypoints can be named with up to 10 characters.
8) You can select the four data fields that display on the right side of the compass screen and the seven fields on the trip computer screen. There are 36 datum to choose from (odometer, bearing, vertical speed, eta, etc...)
9) You can select which pages (and the order of pages) that are displayed when you 'cycle' through the pages. (there are 14 pages, not including the FOUR GAMES. Some of the games are multi-player games that you play agains other RIno users!)
My favorite line from the manual: "Games are provided as an entertainment feature."
