We picked one of these up for Bob, an engineer. I had told Sam we are almost entirely now iPhone focused here, more then a few hundred in our enterprise. However, we have a few users who the screen size of the iPhone doesn't match with their needs (be a 67 year old sales guru, and maybe the bigger size matters) So, I spent the morning fooling with the HTC Titan, AT&T. Here are my thoughts: (1) The response is clean, smooth, fast.. it runs exactly as I would expect it to, connection to exchange is of course a snap and it moves through the day to day functions completely clean. I make no bones about this, in a game of usable interfaces, IOS and WP7 are so superior to Android it isn't remotely funny, and I would never make a Sr. engineer try and learn Android in a hurry.. but they quickly adapt to this. (2) The screen resolution is too low. This is going to be a negative for quite a few people. The resolution, qHD, strains against the large screen size and it should be better for most users. At the same time, the resolution will mean nothing for someone who wants very large and utterly readable text at an arm length. Frankly, at elbow's length, the text on the Titan is still bright and big, and looks very good. The color quality is also very good. (3) Performance is fast and snappy. I never second guessed how performance was going to run on this thing, it just did. I think the Titan needs a boost in resolution, but it moves quickly from tile to tile, it's a cinch to navigate, and if you have someone who struggles with smaller screen sizes/type, it's fantastic for that. Is 4.7" "too big" maybe for some; but for the right user; this is a perfect device.
