Let the hive mind of Engadget get that for you.
"I own an iPhone 3G and I'm looking for a decent speaker / alarm clock for it. I am going to listen music in a mid-sized room, so I want nice quality speakers with solid bass. I also want to use it as an alarm clock, so it would be great if there is such a feature. The price can be low-mid to mid-high range. I was looking at the Klipsch iGroove SXT; it's powerful, slick and the reviews are good, but it doesn't have an alarm clock feature. It's no deal breaker if I can set it up from the iPhone, but I'm not sure. Thanks!"
Yeah I have to agree. O2 saying that its the fastest selling mobile device ever is probably fairly true, because really its the first mobile phone in the UK thats had an "event launch" rather than just sneak quietly out onto the market.
Apple created this huge hype and probably everyone interested in buying one has already gone and done so, whereas phones like the N95 or whatever, they sell loads, but over a much longer period because they catch on through word of mouth or whatnot. The actual sales comparisons will be much more interesting, as will be any drop off rate.
