"How is Windows Phone a joke?" -- Just look at how worked up you are getting. There are so many fails in WinPhone 7 for me to list on this site without a TLDR warning. For a quick, summary, I would say that the tiles are nasty, the black menu strip down one side is a waste of space and a poor design device. On each page the titles and content do not fit on the screen (intentional or not it is awful), I tried the "Try windows on your phone online" experience and laughed so hard I covered my desk and carpet in coffee.
I quote this anecdote often, but it is apt ...
My colleague showed a friend his Android phone, and his friend said "Wow, my contract is up at the end of the week, what should I get", my Colleague said he should try a HTC one ....
A few weeks later my colleague is talking to his friend, who says that he cannot use the phone, it doesn't do lots of things he wanted and that he hates it. Turns out he was sold a Windows phone.
"Unless you're going back to market share, and well, there's certainly an issue there. But how much of an issue? If market share is your yardstick, then linux on the desktop is a joke and you should take a good look at where your life went wrong." -- Oh, quick attack Desktop linux by posting comments into a website hosted on linux. Go enjoy vista you wintard.
"then linux on the desktop is a joke and you should take a good look at where your life went wrong" -- What? Just because I am not using what all the other Sheeple are using ? Now we've come full circle.
