Since early 2009, both Garmin and ASUS have worked together on the nuvifone lineup, some of which are the Garmin-Asus M20 and the G60. Both devices were an example of how mobile devices have slowly streamlined into a convergent device, capable of being both a personal navigation device and a phone. Getting them to work in favor of the user, is different story altogether. The 2010 lineup will see two new nuvifones joining the family, namely the Windows Mobile 6.5.3 based Garmin-Asus nuvifone M10 and the Android-powered Garmin-Asus A50. For now, what we have is the M10 waiting for your scrutiny in this review, while the A50 will be tested at a later date. So if you're still interested in checking out what this hybrid personal navigation device/mobile phone can do for you, read on for our impressions and how it fared in our testing.
