Thats so true about eye-candy. I tried windows 7 RC on fusion, and just turned of all the eye-candy to see if I can get a better performance. What did I get - a just plain old windows 2000 style menu system and tool bars and what not.
I didn't know where to start. No useful programs right out of the box anyways. With a mac, you get iLife programs to start with right away. (and full unix to play with, webserver etc if you are a developer) For windows, I have to download Firefox, Picasa, tomcat etc to have a real useful machine. Since then I never booted up windows 7. Its a lipstick on a old pig. So right out of the box, Mac gives a better experience than windows ever will.
iPad with iWork, oWorks (Omni) (and later iLife) will have a much better user experience than any of the other tablets out there.
iWork on the iPad requires patience and during the keynote with Phil Schiller it seemed almost unbearable to work with other then quick last minute adjustments. If the computing market tells us anything about its user-base we learn that people want faster processing and faster input and recognition. I expect that initially people will live through the slow input and modification of iWork for iPad, however over time they will just not bother using it at all, it will be trivial at best. Just take a look at the 3G versus 3GS debate on speed issues. Though I have hope for Multi-Touch input, at present it has a lag time that I am not accustomed to, even on my iPhone/iPod Touch.
