My impressions, just touching on a few things...... First, as others have said, obviously a former Nokia employee with a grudge. Lost his job due to "Elop'pian" cuts, maybe? The biggest thing I see here is that anytime someone is so full of themselves ("I was the first", "I was most accurate"), I have a hard time giving any credibility to anything else they say, since they've obviously started out with lies.
Here are some quotes that I really like </sarcasm>
Really, I don't see Skype as a problem for carriers. I mean, aren't plans shifting to data plans? I mean I shifted plans from a family plan with unlimited data and 1400 minutes to a family plan with unlimited minutes and limited data. I know I'm not the only situation, but it seems to me that more and more, it's data they're selling, not talk. I mean, can you even talk on a phone anymore? Does Skype work without some sort of data connection? I'll have to do some testing to try that out.......
He says a lot of things that sound like they could make sense, unless you know more than what he's saying. He's not telling you that it was AFTER MS bought Skype that Verizon came out and said they were going to push Windows Phone (and they have). He's leading you to believe that Windows Phone is bloated when in actuality it requires far less computing power than Android.
He's just a sore ex-employee on a rant. Nothing to see here - move along.
