I'm more than happy with the Apple kit bought over the years ... the uni-body Macbook Pro's are simply the finest laptops I have used and own. OSX just gets better and better and is a pleasure to use. I am forced by work to use Windows, however I *choose* to use OSX and FreeBSD everywhere else.
The iPhone 3GS is my favourite gadget for the last 30 years (and I have a graveyard full of tried and failed gadgets) .. very compelling to use, lovely to handle and more useful software available than I can shake a stick at.
I am notoriously tight with money ... I research, try out and spend ages pondering the pros and cons of all the kit I use ... it has to pass tough tests before I splash out on new gear. I won't pre-order an iPad as I want to spend time with one before considering to purchase or look elsewhere. I'd certainly like a touchscreen, A4 pad form factor, always-on, always-connected, style of device - I been looking for such a device since using the Internet in '85 ... is the iPad it or would a cheaper less technically capable "netpad" be a good choice ... not sure yet.
The point is that Apple make compelling devices, it has superb customer service, it has a great feel for physical design and interactive/software design. As someone who spent many years in the field of interface design research and development, I appreciate the design touches that make Apple products so engaging. Its the physical little things like pulsating power lights, battery indicator LEDs, magnetic catches, the seal around the macbook pro screen and even the lack of user accessible battery compartments.
