Why did you buy it? (or any other brand for that matter)
Which one did you buy (gig size and wireless or 3G)
Do you use it often?
What do you use it for mostly?
Do you have a net book or other laptops?
What do you like about it, and what do you not like about it?
Any regrets in buying it?
I bought an iPad because I wanted it and thought I would use it as a media consumption device and I could also get email and do minor web surfing on it.
I bought it when they first came out. 64 gig and 3G. I was unsure about getting the 3G but have been so so glad I did it. On the occasions when the internet goes out or I'm out and about it has been helpful. The other day I was without home internet for several hours and I needed to read email and do some web surfing and I was fine with having the iPad. Also, if I'm in a store and want to price check availability of something online I can pull it out and just check it right there.
I don't have a netbook (DH has one though). I have a personal laptop and an office laptop. I use laptops and the iPads very differently however.
I have no regrets having bought it and love it. It is very very good at some things and not so good at others.
I used to use my Kindle (2nd gen) a lot. I confess I haven't used the Kindle in months. I like reading on the iPad more than I like reading on the Kindle. The big plus of the Kindle is that it is much lighter. I think the new iPad is lighter than mine but still the Kindle is much lighter than it. However, I prefer to backlighting and color of the iPad and that I can do other stuff as well (like listen to music while reading or check my email).
I use the iPad to watch some video either content that I own and download to it or to stream video. I do some minor web surfing with it. However, if I am going to do major web surfing and I'm at home I'll do it on a real computer. The iPad is handy when I am out and about and need to look up something. For example, before going to a restaurant I will often go to the restaurant's web site and look up nutrition info on foods.
I use it to read and send email. I probably actually use my iPhone for this more often but it is nice when reading a book on the iPad to be able to check email. The other day internet was out at my house and I needed to respond to an email with a PDF attachment. Reading the attachment was easy on the iPad and I used my iPad keyboard to write a lengthy response (I don't use the external keyboard often, only when I need to write a lot).
It is nice to display photos to others and I play a few games on it.
I have an external GPS unit in my car. A few weeks ago that GPS (Garmin) sent me to the wrong place. I pulled out the iPad (DH was driving) and used it as a GPS to correctly find the location.
Things I wish I had on it that surprise me: A camera. I thought at first that the lack of a camera wasn't a big deal but a couple of times I've been out somewhere, had the iPad in my hand and wanted to take a picture. I have to put it away and then get the iPhone to take the pic. I'm not getting rid of mine to get to the iPad 2 just for that but it would be nice.
Texting. I don't do a lot of texting but I've gotten used to it for short messages to my DH or kids. Inevitably I'm using my iPad and want to send a text and then realize I can't since it isn't a phone....
Used to I always wanted to have my notebook computer if I went out of town for even a day. Now, my iPad suffices. I actually haven't used my personal laptop in months (so long that I now can't remember my password to it -- sigh).
That said, if I was traveling for longer I would still want a computer for two reasons. I still work part time and for drafting long Word documents I would want a laptop rather than the iPad.
Personally -- I can't play World of Warcraft on an iPad so that would be a deal breaker if I was going to be gone for long.
