I loved Windows as an IT’er and had several Windows phones, ver 5 and whatever the Nokia version was in 2011 or so. Those phones had potential but they sucked all the same. Still have them; one was used in Hong Kong and S.America but cost more than a high end laptop at the time. Windows is rapidly becoming a subscription service and nobody with a business phones needs Windows beyond Outlook. Most agencies in 2010 utilized Blackberry servers for official email communications rather than rely on MS.
I remember having a Windows smart phone in 2003 and I loved it. I had to go to Wikipedia and check dates and there I saw that Apple didn’t introduce the I-Phone until 5 years after MS had their phone OS on the market (Windows Mobile 2002).
