I will call bullshit on the IPhone. Before that was the vast aray of Palm powered smartphones. Minus the multi-touch and running on lower powered hardware. Though just becsue it wasnt running at the ass blistering speed of smell, dosen't mean it wasn't doing the same things. Then tablets have been around since back as far as 1985. Yet again the harware was lower tech, but it was still the same thing.
Sales figures, you are a really funny one. You are takeing a company against another company. That doesn't work in this case. To get a more acurate picture of the sales of computers, you have to take the sales of over a dozen manufatures and compare them to the sales of Mac. So here is how it is laid out. HP, Dell, Lenovo, Pacard Bell, Alienware...and the about 100 different PC manufaturers. They all make computers and do a decent job of it. Though that is not taking in account the people that buy their own parts and build their own comoputers. That is such a large industry, that companies like Altex can sell obscure parts and be open from 0900-1500 and still make a profit every day. IT departments spend weeks on building the perfect PC and then months on pushing them out to the floor. Spending hundreds of thousands of dallars to make one building of the company updated. Look at the facts of the PC and Mac argument. Mac likes to sit in the back of the bus where it is safe and not worry about how things are going on the frontline. They are putting out core i5 and i7 quad cores in the most up to date computers. Those are over 2 years old. My HP, getting to be 2 1/2 years old now, is an i7 with 12 GB ram, 1 TB HDD, and Geforce GTS 250. 2 1/2 years ago it was $1100. Now Mac is putting out the same stuff with lower specks and calling it new an improved. Out dated, no matter how you look at it.
You want to to out on a limb and bring in that they have great support. Out dated, old, well documented. All of this adds up to 100,000 computer users found the answers to the problems long before Mac got "brave" enough to put that hardware in their machines. Meaning some one else did the work and now Mac is swooping in and calling themselves "genius". All because they waited untill the real inventors in the frontlines figured out what all the bugs where and fixed them, then moved on to bigger and better. Adding onto the thought, the support. What a load of crap that is. If you limit the ammount of hardware that you support, then yea troubleshooting is going to be easy. I loved when I took in my Mac that I was working on for my boss. I had replaced his HDD with a newer bigger one. I couldn't get the IWork crap to install, errors every where. So I took it in and was asking the "genius" to help me with the problem. He looked at it, baffeled by the fact that I had 850+ GB left over free space. So with out asking me if I had changed the HDD, he called his supervisor. His supervisor, came over and after looking at the Mac for a few minutes asked me if I had altered the Mac in any way. I told him I maxed out the RAM and installed a 1 TB HDD, to witch I installed the OS and software on, all other software worked without a hitch by the way. He then told me that he could not help me with the HDD. I tried to explain to him that the HDD is not the problem, the siftware wont install. After about 30 minutes of babaling about the HDD, he finaly said that the HDD is preventing the software from installing, that I have too much free space, and that it is not an approved HDD. To fix this I must reinstall the old HDD and purcase an external. To witch he started "selling" me an external HDD. It ended, after about 4 hours, with them giving me my money back and a cheap ass 4 GB IPod thing. Being that I have a MyTouch 3G with a 16 GB SD card that I am about to upgrade to a 32 GB, I gave that away to my little sister realy quick. The point is, if that is the kind of service a power user gets at a Mac store, that is a really sad state of afairs.
