I cannot believe people still use the festering pile of dung called Outlook. No wait. I can. My friend won't relinquish his grip on it despite the numourous times I have tried to wean him off it and telling how bad it is.
I guess it's like wearing those old, frayed trainers. They may have leaky soles but they are comfortable and you don't like to change them until they fall off and hurt your feet!
