A few months ago I switched from my beloved and battered Blackberry to an iPhone 3GS, mostly to compare the differences.
I am not sure I have completely sorted out my views but here are my basic thoughts.
The iPhone is more fun, much better for the Internet, better as an MP3 player, and has a wide range of really useful apps. Many of its features are really easy to use.
By contrast the Blackberry was more limited, but much better at what it did. The battery life of the Blackberry was great, several days of normal use. The iPhone battery does last a full day of normal use (although its normal use includes more uses). The Blackberry is much better for email, with its SMS system it does not need the Internet and means you are much less likely to run up a major bill whilst abroad. I found typing was much faster on the Blackberry, the Apple's touch screen is not very forgiving to my fat fingers, whereas I had developed a two thumbs approach on the Blackberry that was both accurate and fast.
So, will I be changing back to the Blackberry? No. If I have wi-fi access the iPhone's internet is just too much better. Tweetdeck on the iPhone is a much better way of working with Twitter. And, I am listening to many more audio books and podcasts than before. I am even finding the camera useful - it is so easy to take a picture and send the image straight to Twitter.
What do you think? Blackberry or iPhone - or would you recommend another phone, perhaps an Android?
