On Wednesday morning, my shiny new iPhone arrived on my desk. I've been feverishly using it ever since, and the extent of my fever became apparent today when I compared my data usage with MacFormat's editor, Graham.

According to the iPhone (Settings > General > Usage > EDGE Network Data), I've sent 9.1MB and received 60.2MB of data over the cellular network, and that's just since Wednesday morning. Graham, who has had his iPhone since just after its UK launch, has only transferred a total of 38MB. I've therefore used twice what he has, which clearly indicates that I have a problem and should really calm down.

A quick straw poll around the office suggests that yes, I'm an unsually heavy user – great news for me being on O2's unlimited data plans, as otherwise these two days would have cost me a fortune – but I'm curious to know how much of a freak I am.

So let us know how much data you've used if you have an iPhone. There's no way to measuring this against how long you've had the phone, but given that I've used twice as much data in two days than most of my colleagues since the iPhone's UK launch (and before in some cases) I somehow think this is less relevant. So let's go; add the Sent and Received figures from Settings > General > Usage > EDGE Network Data together, and let us know in the forums how much of a data junkie you are.

No, nothing sinister. But I did learn an important fact yesterday: if you don't want people to read the emails you're writing, don't write them on an iPhone.

See, I've just bought one, and had it with me yesterday as I went through to London for the launch of Canon's Spring collection. And everywhere I went, if I was writing an email on the device and there was someone sat next to me, they'd be watching me type in fascination. Sometimes it was a sly sideways glance, sometimes it was an open gawp, and sometimes it was followed by a shy "is that an iPhone?"

And while I was happy to demo it and hopefully convert a few more PC heathens, I just wished it wasn't when I was writing an email to my wife...

For those of you of an inquisitive and/or destructive disposition, Gizmodo has posted a video of a MacBook Air being taken apart. Not sure about the incidental music though - sounds like early Kraftwerk...

***Stop Press*** The video and accompanying pics were removed by lunchtime on Friday 25th at the request of Apple, but Gizmodo is promising to repost once they have their very own MacBook Air.
