I used to love HTC and have had many HTC phones over the years. Now HTC is doing poorly and everyone says they don't know why and others are mad that Nokia keeps releasing exclusives. I think the reason HTC is doing poorly is because they only like their flagship phones on each platform. I have friends that have the Radr and the One S and both have really annoying and pretty substantial issues that many people complain about yet HTC does nothing to fix the issues. The Radar seems to have a lot of issues txting and the One S has reboot issues. Looking here I didn't see much about the txting issue on the Radar but in the Tmobile forums both of these issues are widespread. In a txting world having txting issues is a serious issue and having your phone reboot several times per day is really unacceptable. I no longer feel comfortable recommending a non flagship htc.
