I'm looking at upgrading from my Treo 650. I'm really quite happy with my current Treo, but the EDGE only speed may be an issue since I'm hoping to tether with 3G speeds against a new phone.

My question has to do with how the Windows Mobile apps stack up against KeySuite when it comes to Outlook syncing. I'm extremely happy with how KeySuite works and I'm wondering if the windows mobile apps stack up favorably against it. I know Pocket Informant or Agenda One are popular substitutes...do they match up or would I be disappointed if I switched?
