This has been very true. I remember when I went to a local AT&T store when my upgrade came available, I was tore between an Android phone (don't even remember which one now) and the LG Quantum.
When I mentioned my choices to a sales rep, he pushed for the Android phone, saying I'd be disappointed with the LG, cause it didn't have as many apps and blah blah blah. I told him I was a big Xbox Gamer and liked the connectivity that the phone had, plus it didn't just look like another iPhone copy-cat.
Anyways, he just continues to push the damn Android and finally I just said, I don't care, I want the LG. I like the WP7 OS better, the slickness better, the heft (it really does feel like a solid built phone), the rubber finish and of course, the slide-out keyboard. The entire time he rang me up, he just had this "you're making a big mistake" attitude with me.
Now, 3 months later, I can't be happier with my LG Quantum and WP7. And yes, I have played around with iPhones before, and never liked the cluttered mess of apps that made up the "desktop", and Android phones just never felt user-friendly. It's sad that there isn't more attention paid to WP7 devices, because it's been a breeze using this phone. I wouldn't trade it for anything..... ok, maybe a new Mango phone, but I'd just be happy with the update for now.
