> I've never read so much crap...
Your illiteracy isn't something about which you should be bragging. Learn to read and then read about Microsoft and you'll read lots more crap than you ever thought existed -- all earned by Microsoft through its incompetence at software engineering.
> I bet that all of them hadn't tried Windows phone 8
Your wagering skills aren't something about which you should be bragging. Windows Mobile has been a scourge since 2002 when Microsoft owned the market, and lost it through sheer incompetence and bullying. Nobody's left around who would try "Windows Phone 8" or whatever Microsoft releases now because they've had 13 years to fail to corner the market -- and all they've done is demonstrate the wrong way to do things.
> The phones are great. The OS is excellent and works well on low end phones too
Your analytical skills aren't something about which you should be bragging. The phones -- hardware wise -- compare poorly with one and two year old Android or IOS phones. The OS is hardly stable, and the app store a joke. Yes, it works well on low-end phones because it is a low-end OS that doesn't push hardware to any limits -- fortunately -- because the hardware it runs on IS low-end phones.
> Cortana is brilliant
Your girlfriend in mind only. You really should look up what "brilliant" means and realize that an artificial voice recognition software can't be brilliant. Then if you decide to learn English and use an apt word like "useful" you'll find that anything with Bing as the search engine is an exercise in frustrated futility.
> Just look up the specs of the newest Lumia 640XL
Perhaps you should "just look up" that this is a discussion about Microsoft potentially acquiring BlackBerry, not a discussion of how much they suck, or how awful they are, or how they took Nokia down the proverbial tube. The Lumia phone is history. It just hasn't got there yet.
