If you've done it please let me know your experience. I'm worried about downtime or any problems like spam on iCloud. Gmail has been extremely reliable for me over the years. I'm considering switching as I'd love to have a single account when I setup my devices. Right now I have 3 (Exchange for Push e-mail, iCloud for Reminders, Gmail for Notes) and I wish I could just have 1 as I'm sick of having it so confusing. Simplicity is what I'm trying to achieve. Tried getting Push working for Mail in OS X(for my Gmail account) and just wasted a few nights with no luck, it sort of worked but wasn't as reliable as it should be which has led me to consider switching completely over to only an iCloud e-mail. I know there are other threads asking the same question but I wanted to ask it as of today, Dec. 2012 how the service is. I'm guessing over time the uptime gets better, the spam filtering gets better so what maybe wasn't that good 6-12 months ago could be pretty good today.
