I am currently using Comcast for high speed internet. I'm happy with it except for the fact that Comcast only supports pop, not imap. Now that I have a iphone I sync email with it. After doing some research I found out imap is far better than pop when used on multiple devices and eliminates the problem with syncing. We have Qwest dsl available here with msn and I am going to check with them if they support imap but I think my best option may be able to subscribe to .mac. I know many parts like photocasting I won't use. The iDisk is also too small for me. I've heard Leopard will add features to .mac but I like both the syncing part of .mac and also the fact I get a .mac email address and it is imap. Since this will replace comcast as my primary email which I use a lot daily for heavy use I am wondering if it's very reliable, works fast, etc. I would set it up on my iphone and in the mail program on my Mac but I want to make sure it's very good before I make the switch.
