I have an iPad I love it!!! Even though I preordered it, I still had to wait in line at the downtown Chicago Apple Store for about 45 minutes (I thought I could just run in so I parked in front of a church and put up my flashers chicago style). Overall its not so much a game changer as it is a good tool and moreover, an amazing piece of technology of the future - the first of its kind. I did not get the 3G version because I really have no intention of taking it out of my house. Especially the neighborhoods that I frequent for real estate work, I wouldn't dream of bringing out the iPad. I have it at home or I bring it to my office and I use it to read the news and surf the web, watch movies. Its not really good for "working" because the typing is not that good, but its great for surfing the web. And yes, at least the Northern Illinois MLS looks great. MRED has put a lot of effort into making all MLS related stuff iPhone, Android and iPad friendly. Good Reader is a good app for reading books or pdfs that you ahve downloaded. I sync my computer with the iPad with Dropbox (I also use it to hook up with my office computer). Dropbox is an amazing web-storage program also.
The game changer is that Apple has always been the trendsetter and the seeker of new market segments. Apple literally creates markets for themselves - for example the graphical user interface, the single form computer iMac, the iPod, the iPhone, etc. In all of these markets, Apple has either created a new market, or significantly expanded the market. For example with the iPod, sure there were huge music storage devices like I think there was one by Soundblaster it was blue colored kindof looked like a portable CD player... at the time everyone was still listening to CDs, and then with the iPod they expoloded the personal digital music market with the easy user interface, the chic form, and jazzy marketing. That led to smartphones - sure there were phones like the Blackberry that did your email, but that was really marketed towards Wall Street and business and not really to the masses. The iPhone was really the first phone that did "everything." The entire package was there - the interface, the apps, the marketing...
I believe that the iPad is a trend setter in that way. In 10 years, I bet 40% of all computers sold will be like this. Its like Star Trek. They might as well use iPads on the Star Trek set for perfect product placement. This has opened up a new market for computer manufacturers. There will be lots of very excellent copies, eventually we will have full fledged computers on an iPad form. Maybe not by Apple, but perhaps within 2 years or so, someone else will create a full Windows computer that is in the form of an iPad. Its only a matter of time. This is the game changer, the creation of a new market. Without the iPad manufacturers would have never known consumers would enjoy such expensive and extravagant personal technology, and have the prerogative to create them. Now they see the money is there and they will compete with Apple, and create incredible products (maybe the typing will improve and it will in fact be practical for work).
You have to admit that Apple, is in the business of setting the trend. They are kings! They are like the Gucci of the computer world - everything they create becomes what is the norm in a few years.
