My HTC Radar is for sale on eBay. That's not because I dislike the WP platform. I think it's pretty good, and has a lot of potential. I bought it and used it for a few months to give it a fair trial. I'd recommend WP, and the Radar in particular, to a lot of people, but it had a few shortcomings that were problematic for me, specifically. These things come down to individual priorities. Things that are obstacles for me may be irrelevant to someone else.
Case in point: The inability to set a default font size in the browser and then zoom and reflow text. For me, an eyeglass-wearing 58 year-old, this severely limits the usefulness of the browser. Turning the device to landscape orientation helps sometimes, but not always. So as a general thing, if I needed to do any significant amount of reading of text on web sites, I'd use my BB. And yes, I know that the iPhone doesn't have this feature either. That's one reason why I don't have an iPhone.
As I say, I think WP has great potential, and I may return to it. But at this time, it doesn't make financial sense for me to have a phone that I'm mostly using to play Wordament, and doing most everything else on my BB 9900.
It's not about love or hate; it's about finding what works.
