Paid up member of the Apple fan boy club here. I’ve got an iPhone and a Blackberry pearl (for work). For web browsing there isn’t anything better than the iphone. Email is about as good as the Blackberry – but the interface is much nicer. For making calls its OK, but not as good as Nokia’s I’ve had and the battery life is carp.
The link with iTunes makes it easy to use as an ipod and watch videos on. You can only use BBC iPlayer on it with a wifi connection. And there are loads of 3rd party applications including some pretty good games.
If you can swallow the relative cost and live with the carp battery life go for it. If you can’t then I’d go for a Nokia with push email.
I don’t rate my Blackberry, but that because its a gayer Pearl and not one f the Alpha Male Storm or Bold varieties 😉
