I understand the Treo 600 has polyphonic ringtones like the 300 and 270, but I'm curious about the quality of sound. When comparing my Treo 300 to other polyphonic phones like the Samsung A500 and N400, their ringers sounded much more realistic. To compare them, it was almost like listening to a regular midi on a computer, they had a wavetable card (old analogy I know) and I just had the regular fake sounding midi synthesizers. I'm curious if anyone's heard if the instruments for the Treo 600 have been improved.
