Had a little extra cash that came my way over the past few months. It was almost enough to cover a 64GB iPad 3G/WiFi, so I decided to go with that.
A few thoughts on being an early adopter:
1. I completely realize that Apple will make a better v2 and then a v3 the year after that and so on. That's the nature of the beast. You can say the same thing with every PC, Mac, HDTV, automobile, digital camera, etc, etc. At some point you just buy it and understand that you'll replace it. I'm not sure why people are so focused on the fact that Apple upgrades their equipment annually when nearly every company in every industry does the same thing.
2. On a related note, I have an iPhone 3GS and my original iPhone. Now my son plays with the original iPhone, and I use my 3GS constantly. Again, that's just the way it works. Presuming Apple releases a new iPhone this summer and it is compelling, I'll probably get that and give my wife my 3GS (though my son has his eye on that

).
3. I'm expecting to use my iPad in the living room and probably the bedroom for reading, surfing the web, gaming, watching movies, etc, etc. I also expect to use it on the road/vacation instead of bringing my Mac laptop. I think it will be a great "in between" device as I rarely need all the capability of my laptop while I'm on vacation.
4. I also expect my mother - who has never really used a computer - to get one. Like other "seniors" she knows, she wants to have email, web, photos and very occasional document writing. This seems like a perfect device for her rather than a full laptop. I really don't want to have to be tech support for someone that has never used a computer. The iPad should make this a ton easier.
5. I recognize the iPad lacks some features. The biggest missing hardware feature is a forward facing camera for video chat. That said, in all the years I've had web cams, iSight, etc, I've probably used video chat less than a dozen times. Most of the other missing features are software related. Multitasking is rumored to be coming, and Flash will likely never happen.
So...based on all this, I figure, "why not get one now?" You can play the waiting game forever. At some point, if you want one, you take the plunge.
Not sure why I felt compelled to explain all this, but I do tire of reading all the "iPad is a waste of time, money, etc" comments.
