Apple has more profit from PC sales than the next five Windows PC vendors *combined*. (Image from asymco.com.)

I appreciate this. Business people should think in profit, not revenue, but most state revenue. At my software firm, our revenue was only $2M annually, but our profit approached 25%. That's the same as a $10M/year firm with a profit margin of 5%, with a lot less risk.

I just read on techradar that both T-Mobile and Orange have reduced their iPad prices, most likely to reduce inventory for a new iPad 2 model. This is of particular interest to me, because I've been reading a lot of books with the Kindle software lately, and I'd like to buy an iPad soon to make that reading experience more enjoyable.

I was just chatting with my oldest sister, and we were talking about companies who are currently hiring. While looking at that list, my sister casually mentioned that there is another name for a financial advisor: "thief".

On a whim, I went to Monster.com and typed in "thief", and found these job listings:

This NY Times article gives a little idea of operating systems sales on mobile phones. From this article and other sources, it looks like Apple thinks they will sell around 10M iPhones next year (either next year, or in the first 12 months), and Microsoft is projecting sales of 20M Windows Mobile devices in 2008, both of which were announced before Google's Android announcement today.

IDC released PC sales information for the 2nd quarter of 2007, and shows Apple with a 5.6% share of all new personal computers shipped in the U.S. This puts them in fourth place in U.S. sales, in a virtual tie with Gateway, and in front of Toshiba and Acer. Dell and HP are in first and second, respectively. HP, Apple, Acer and Toshiba are up, Dell and Gateway are down. Apple may gain more ground and pass Gateway, but lose position to the hard-charging Toshiba and Acer.
