I believe people are asking too much for Apple to make things like these standard. Not many other PC makers even have the option to put in WiFi/BT into a desktop. Apple should not make them standard in my opinion.
But I don't like how now on the Powermac you must order both or none. Before this revision you could order the BT and Wifi module's seperate or buy them together for a savings. No you have to get both even if you need only one.
