On the specs pages for the 2 Airis PDA/GPS models I see that the processor model for T610 is shown as Samsung S3C2440 (300 Mhz) and for the T620 as Samsung 2440 (400Mhz).
- I am not sure if the similar looking processor numbers are indeed 300MHz and 400MHz respectively.
- I do not care about bluetooth and wifi as I intend to use the unit only for navigation. In regards to that will a software like Iguidance 4 see any noticable speed and screen refrsh etc. differences running on the T610 vs the T620?
