Been reading all the buzz here about the 600 and have been waiting not so patiently for the GSM version to be available. Today, went over to the local Sprint store to see the demo model the store just received. All I can say is Wow. Rock solid design, the 5way rocks, screen is super bright, seemed speedy enough. I'm very impressed. The feel of it in my hand was superb. I'm using a T3 and Siemens S56 currently, and have been debating whether to stay with that setup or go with the treo. Having held it in my hand, I can say without doubt that it's the best designed smartphone I personally seen and I'll probably be picking it up soon.
