Don't think you've really 'got it'
The iPad isn't a replacement for your laptops.
It is a great device for certain things which beats a laptop hands down. For example, lightweight browsing is great in portrait mode. I wouldn't use it for research, but a general poke around the web is fine.
It's instant on with no effort, meaning that I think "I need to look that up", I grab it, it's instantly on, I look up the thing I wanted to know about. Compare that with a lappie; it's got to be opened, switched on (fast on a Mac, less so for windwos), placed on your lap (it's got limited places where it'll work), fire up the browser, search. For me, the iPad is just a lot easier for casual use.
It's form factor is massively better than a lappie in certain circumstances. On a train/plane/automobile. Standing up. Portrait mode is much better for reading. Laying on ones side whilst reading in bed. Landscape mode for more detail, typing and films. Lappies don't have orientation choice.
An iPad is rubbish at doing multi-tasking 'work' things such as taking notes whilst reading a document (it's single-tasking user interface won't allow that). It's rubbish for long typing sessions, although it's fine for email, etc. The limited functionality of the browser means you're not going to use it to develop websites, not view sources. The 'odd' layout of the keyboard gets on one's tit - lack of tab or cursor keys for editing.
I paid £730 for mine and am delighted with it being a great device to AUGMENT my large 17" lappie, particularly when commuting, watching the telly, reading in bed, etc. It ISN'T A REPLACEMENT for a lappie. This is probably where people who 'don't get it' go wrong.
The fact it was given to you means it has little value to you. Why not give it away to someone who would value it, or even drop it into a charity shop.
