i've got the 1.35.404.4 NLD with ROm Date 05/30/08 and radio 0.93.25.NS26
Love it. Some critics nitpick on it. Well, get a Garmin, get a Nokia, get an Asus, get them all...

This is a real all-in-one with GPS, GSM, FM radio, MP3 player, PDA, USB stick, modem, blackberry,... (well euh... the diamond pro?).
It can be tweaked for better touch sensitivity, faster running, etc etc... and its programming is free (no iPhone hacking tools required).
It runs nice out of the box, and even better tweaked; And yes, a Garmin Nuvi boots faster (just a little I guess) and runs longer while some Samsung GSM menu's pop up smoother / quicker. So? The first plays my music too and connects to a BT set, but can't make phone calls on its own and the last one has FM radio onboard and 3G. But you need the both together to get the same features. Imagine walking in public with your pants exploding from gear (euh...


)... well you know...
More business => Diamond Pro.
More of the same: yes, in nearby future.
common good? In about 5 years?
Getting better? Hardly, probably faster, longer batterylife, bigger memory, expansion slots and hopefully USB host and 802.11n and so on....
