I'm really sorry to have to say this, but I'm going to have to stay with the iPhone.
I was so ready to ditch the bloody thing - not because of any design flaws, simply because I resent the way Apple dictates to you. I'm a PC man, in case you haven't worked it out yet.
The only reason I got an iPhone in the first place was because there was absolutely nothing in the same league. Then out came Telstra's new plans and with them, the Desire. I had no choice but to take a Desire, use it side-by-side with my iPhone, then decide which one to keep and which one to sell. The HTC is going on the market for the following reasons:
1. Battery life. The HTC battery life is truly appalling. I thought the iPhone was bad. This is much, much worse. Not only does the battery meter go down as you watch, but the recharge time is far worse than the iPhone. Hours. The iPhone at least recharges quickly - very quickly in fact.
2. Availability of apps. The App Store is overflowing with high-quality, useful, applications (admittedly, there are still a lot of duds). The Android Market is bare. What apps are there, have no quality control. At least they have a refund option, and to be fair, the Android API offers a vastly (potentially) more useful array of apps, like switches to turn off wi-fi from the home screen. But they're light-years away from the quality and variety of the iPhone apps. It seems that, currently, Apple's Nazi-like approach to their app market has at least one benefit for the buyer - they are able to enforce a certain level of quality, and developers have run with this.
3. GUI. The HTC Android interface is just not sexy. The iPhone is uber-sexy. The other thing that really pisses me off, is that when you check an option in an Android dialog box, it often closes before the option gets checked. This makes it look like you missed the check box. So you have to go back and make sure you didn't hit the wrong spot. Sorry, Apple wins again.
4. Audio. The iPhone is definitely louder than the HTC. It also seems to have more bass - from a speaker that can hardly be bigger than a mustard seed. The HTC audio is tinny and weak by comparison.
Maybe in another 6 months, HTC/Android will have caught up, but for now - no comparison. Apple, thumbs up. HTC, sorry, but no cupie doll.
