This Inspire is really not nearly as good to me, as compared to the Infuse. I had the Inspire for 3 weeks, and the buttons are recessed into the phone, and very awkward location on the lock/power button, and also it is almost flush with the phone making it hard to unlock. Also the volume rocker has no tactile feel either, you can't tell when you are pressing it. These buttons actually get pressed in more, the more you use it (as reviewers will say too, its true). And the phone was not as smooth scrolling through pics, menu's etc as the Infuse. I did the "buyers remorse" they call it, and took it back for the Infuse. After 2 days, I am ecstatic about this Infuse. It is SOOO much of a better phone, I have absolutely no regrets. The Inspire is also a brick, and when carrying in my slacks it was very heavy. Also the rounded case made you pick up the phone to text, otherwise it wobbled on my desk back and forth as I texted. The Infuse is flat so I can text on the desk without picking it up. And the camera on the Inspire was bad, I could never capture a picture where it wasn't a little blurry, Infuse doesn't have that problem as much. And the Inspire camera sticks out too much. I did like the way the icons looked on the HTC more, as they looked more modern (HTC Sense I think it is called), but every other aspect the Infuse is better. I am SOO glad I took the Inspire back, and don't regret my decision in the slightest. Also I have 3 email accounts and an Exchange account, and the Inspire was Extremely awkward to get to the accounts, the Infuse handles it awesome and is SOOO much more user friendly. Also the screen is more responsive on the Infuse than the Inspire, feels much more like the iphone screen (sorry, but the iphone screen as far as touch sensitivity goes...beats any android phone, that is the only thing I will give Apple Kudos for)
Also the G2 as stated below is dual core, but also 4.3" screen not 4.5". And phonedog tested Infuse and G2 side by side, and said they could not tell a difference between the speeds, and said that the programs do not fully benefit from dual core yet, and the battery drains faster etc because it is the same size battery as the Infuse. I can only see a possible benefit in gaming, but I don't game on my phone, so no benefit to me waiting for G2 to come out months from now. Only big benefit I see is G2 comes with Gingerbread out of the box, Infuse is Froyo. But by the time the G2 comes out we might have GB, let's keep our fingers crossed!
