I have been a macintosh user since the days when we still called them macintoshes.
We had our first mac desktop in 1987, and I've never owned a pc. I love my iPod and my macBook, and I even love the iPhone commercials.
Naturally I have been drooling (in a polite, non-sticky, lady-like way) over the iPad since they came out. Imagine my delight when my 78 year old grandmother handed one to me! She wants me to "learn" how to "work" it and then show her how to check her email. She handed it over in a hand sewn cover. I love her.
I've had it about a week now, and I am prepared to make a formal review.
The iPad is totally lame.
It's fun to touch and manipulate things on the screen, and for me, it's a very intuitive interface. On that front, I'll give it full marks. It looks pretty. Unlike the iPhone, however, you need to be near wi-fi to do anything cool with the iPad. You can't store or open files independently from iTunes (like a paper from school, or a picture file from my aunt). That means that checking my email on the iPad is pretty much useless. I can't read pdfs, or use any webpages that utilize flash. After a few minutes of watching youtube, my wrists got tired from holding the remarkably solid tablet at a proper viewing angle.
It's probably perfect for someone like my Grandma who will use it to respond to family emails, check the weather on her accuweather app, and read headlines from USA today. But is that worth 500$? Not to me.
