With my new job vastly different from my last (programming vs. coordinating), my need for the PDA function of a smartphone has dramatically decreased. Now I am more interested in getting an improved cell phone than an all in one smartphone.
I would love to go back to Nokia as I had great experiences with their phones but none of the phones in their current lineup (that works in the U.S., i.e. tri-band) take my fancy. So I turn to Sony-Ericsson again and the Z600 seems to fit my requirements. I especially like the built-in antenna which is one of my primary reason for not liking flip phones.
Despite receiving great reviews (MobileBurn and Mobile-review.com), none of the U.S. carriers have plans to supply it officially on their network. And with my T68i locking up randomly throughout the day, I am forced (!) to purchase an unlocked Z600 when my first paycheck arrives later on this month.
