Been there, done that. Didn't really work out like I thought it would.
The iPad needs the iOS 4 update BADLY- the lack of multitasking is really a downer, and as a result, I'm 10X more productive on my laptop. I really wanted to use my iPad as a MacBook replacement, but it just isn't. I'm tech-savvy and all, but I just can't make it work. I think the situation will be much improved with iOS 4 (Apple did a great job with its multitasking framework, it's really a gem on my 3GS).
Although I'm annoyed at Apple for only providing us with 256MB of RAM, especially when they were designing the iPhone at the same time with 512MB (that's for a device with a lower resolution display), and at AT&T for their 3G bait and switch.
I'm not a happy iPad owner for these reasons, but I'm keeping my fingers crossed that not only will we get the all the iOS 4 features that iPhone users enjoy, but that we'll also get some innovative UI improvements that will really make the iPad useful.
