Wow. Somtimes a thread can get a life of it's own, can't it? What started as a thread on reps not supporting Windows Phones ended up being a discussion on what market segment WP can get. And by the way: I love WP Central because very rarely is there anyone taking cheap shots at each other even as they disagree. In the internet world, that is unheard of. Thumbs up to everyone.
First off: Welcome gavinsane. And I hope your Dad gets years of use from his HD7. Your experience is sadly not new, but happily getting better. I choose not to go to my AT&T store in my hometown, but instead hit one in Champaign IL due to their knowledge of WP. Not all sales reps are good, but they are improving. As for the huge electronic stores, I have zero use for them. I lost my mind at a Best Buy last year when I heard a salesman telling a middle age couple to not get the Blackberry that they wanted because they were bought out recently and didn't even make their own phones anymore. Just appalling.
As for marketshare, WP better be aiming for the sky and trying to get everyone. They are still in single digit sales worldwide, and that is plain their fault for not competing harder. Yes, they can get the feature phone crowd. They can get a portion of the Blackberry crowd that is leaving in huge numbers. They can get Android users. How, you say? Low end Android users are not all happy. There are a ton of horrid Android phones out there, and Microsoft can very well push to them how much better WP is as an experience.
No, they cannot get iPhone fanatics. But, no one can. No, they will not get the user on Android who is a heavy tech fanatic. Android's open source allows for tech advancement faster than WP ever will. And right now, WP will not get the app-driven consumer. 50,000 apps in one year is great, but can't compare to Android and iOS. And unless MS starts to allow and maybe require higher end WPs to have better storage (32gbs), they will be hard pressed to get the music/gamers/movie watching crowd.
But other than those four groups, WP can take ANY user away. It is that good, in my humble unimportant opinion. Microsoft just has to get after it.
