If you want one because it is cool, then you are wasting your money. But if you want a mobile solution to access the Internet, your mails, play some games, do some work, it's an investment.
My feelings were the same before I got one, it's a big iPod touch/iPhone. I already had the iPhone 3GS when I put my hands on the iPad. Guess what? I now use my iPhone as a phone and to play some music like an iPod... Everything else is done on the iPad now. For me, the biggest features are:
- mobility
- great battery life
- great display, a lot better than reading on the iPhone
- larger virtual keyboard, easier to write stuff
- always ready to use, not like laptops/desktops requiring booting time and login
- great for watching movies when traveling by bus or train
Also, I can tether to my iPhone for Internet access when there is no wifi available (it's a wifi only)
My laptop and desktop are now used for storage and development only. If your not into flash based games, then your good to go ( lots of flash based games are actually available as native apps)
And the prices for apps and games are really lower than what you find on Windows for example. I got Pages for 10$, and I could get the whole suite for 30$... MS Office cost much more than that, a bit high when you are writing basic documents...
Go to a store, hopefully an Apple Store and play with one. It's not a laptop nor a desktop, it's a tablet. Depending on what you want to do, you'll see benefits.
