IBM.. you must be referring to the ThinkPad, not the IdeaPad or the G series right? The Thinkpads are great business machines, but they are never associated with "sexy" or "attractive", they focus too much on business and stability and they are always behind in terms of specs.
To answer your question, first Macbook (Macbook 13-Inch) with Intel Core Duo T2300/2500 is in 2006. In Late 2006/Early 2007, Apple introduced the Core 2 Duo T5600/5800 CPU. In Mid-2007, Apple has the T7200/7400 Core 2 Duo. In Early 2008, they started using T8300 with X3100 graphics. Late 2008 is the first introuduction of the Unibody with nVidia chipset.
To say ahead, take Mini-Display port, derived from the Mini-VGA and Mini-DVI used to be Apple exclusive, now it is on its way to replace standard VGA/DVI port. hmm... USB and Firewire was used in first CRT iMac in 1996. The only thing I think PC has and Apple does not is eSATA and Blue-Ray, which Apple exclusively does not support at the OS root level.
Again, I bought my Mac is not because I really love a Mac, I just simply love how things are built on the hardware level. My next laptop will be an Unibody Mac for sure, because I have yet to see anything that has similar spec with 7+ hours of battery life.
With less than 10% of market share, the reason behind Apple success is innovation. During the design process, if the product does not meet Steve's standard, it does not go out to manufacturing. Unlike many PC makers now rely on Taiwanese ODM companies to do the design, and what you get from PCs are just something the different vendors put together with a label.
To be honest, I get to deal with computers and stuff. Apple is the only company that gives me the excitement when something new is announced. When I see a new HP and Toshiba, I just like... all right... just another PC. PC is dull and boring, but they are easy to do. Mac is exciting yet expensive, I remember I broke a cable in an iMac and I need to have the whole front bezel replaced... neat eh? That's exciting when you need to know what you are doing, and it's different on all models.
