Decent points, but you don't HAVE to manipulate anything extra on the iWay to get from Point A to Point B. In terms of usability, I could argue that the iWay is
at least as easy to use the basic functions of a GPS than the Zumo (especially with my skins

,
many functions are
much easier on the iWay and many functions are currently impossible on the Zumo)
This was pretty clearly shown on my videos where I performed the same functions with multiple units.
I still agree - most entry-level users will be very happy with the Zumo and it offers many things that the iWay can't touch: Bluetooth, removable memory, battery operation, manageable size and most importantly:
DEPENDABILITY (hopefully - it's still early)
Personally, I can't get past the inability to manipulate the map screen if you're not routing, the maximum 80' zoom level (which makes working w/POIs difficult, if not impossible) and many more niggling issues that most people don't even consider when they're contemplating a GPS, but I've been spoiled.
If the potential QC issues or bulk of the iWay concern you, by all means - get a Zumo.
