the speed and quality of its Internet browsing experience (13%). A second major dislike was the size of the keypad (11%), with owners complaining that the keys are too small and cause too many typing errors. "The overlaid keyboard (two letters per key) and TrueType feature make my BlackBerry slow to type messages without errors," reported respondent PET91787.

The Apple iPhone

By far the most lauded feature of the Apple iPhone among owners is its seamless integration of a phone, iPod and Internet browser (36%). As respondent DSL06271 puts it, "The feature I use most is the iPod, but it's the integrated whole that makes it so much fun to use."

Respondent BOB04545 adds, "I love the iPhone. It is revolutionary. I love being able to jump on the Internet, send email, get maps, weather forecasts, instant message, and make phone calls."

The second most popular feature is the iPhone's touch screen interface, followed by its ease of use.

In terms of dislikes, there is no doubt about what iPhone owners hate most. It's the speed of the AT&T EDGE network. No surprise then that the number-two criticism is the requirement to Use AT&T.

Users also expressed particular unhappiness with the iPhone's lack of copy & paste functionality.
