Gmail was a breath of fresh air when it debuted. But this onetime alternative is showing signs that it's past its prime, especially if you want to use the service with a third-party client. That's the way Google wants it, which is why I've given up on Gmail after almost a decade.
Personally, I've always thought it odd that no other email provider ever adopted Gmails "search not sort" mentality. I've been a Gmail user since you needed an invitation to get an account. However Gmail has been steadily moving towards a more traditional email experience. Plus there's the iGoogle disaster that got me looking into alternatives to everything Google. Will this be the wake up call Google needs to get its act together and stop being evil?"
