Tablet, huh! yeah! what is it good for!?... No seriously?

(in short) This is mostly a question for desktop/laptop/desktop+laptop users that got a (full) tablet (i.e. no kindle, nook, or whatever Walmart sells for $99) - have you found a proper use for it? Something that would justify for example getting the new ipad (regardless of what your current one is)?

My story is a "sad" one (first world problems and all that jazz). I got the original ipad almost as soon as it came out. I'm a gadget geek, it seemed like an exciting new product and I wanted, at least for once, to be at the "cutting edge". But while I've used it on occasion, when it comes down to it I can't find a use for it.

I enjoyed the touch-based big screen browsing and emailing and twittering and what not, and I got a kick out of some of the games (mostly the casual types like cut the rope and the like) and I've been impressed with software like flipboard, imockup and garage band. However, at the end of the day I found that for everything that I could do on an ipad and that I needed to be able to do (i.e. garage band is not something i need), I could do it (mostly) better either on my desktop or my smartphone.

When I'm at home I simply don't need the ipad. It's like, why would I do email on it, when I have an awesome keyboard on my desk to do it. Why would I browse the internet on it when I have two 24" IPS screens to do it on. Why use imockup or ipages or whatever when, again, I have a desktop with photoshop and word. And gaming on ipad can't really compare to the experience I get on my desktop, Infinity Blade or not.

When I'm not at home I have my smartphone with me so stuff like email and whatever social services I use are easily accessible, casual games (the ones that I find fun on a touch device) are also available, and yeah the bigger screen makes them better but not enough to justify carrying the ipad with me everywhere.

There are only really two uses I found for it and both are flaky.

One, is using it in bed at the end of the day. It is nice to check up on some blogs (via google reader) or watch a show lying in bed. But again, doing it on a desktop is not really a big deal in terms of physical convenience, on the other hand, if I want to comment on a post then on the ipad most likely I won't be logged in and I have to get up and look my password on the desktop anyway, and then of course the typing of the comment itself. Only watching shows ends up having more pros than cons, in this context.

The other use I found for it is that, because I don't have a laptop I sometimes would use the ipad as a way to show a client some design mockups, but it's not ideal for that either, and I'm getting a laptop soon anyway.

So yeah, I don't mean this as a way to criticize ipad, or any other tablet for that matter since I feel the same way about android tablets. And I don't mean to say that tablets are useless in general. I completely see their use for some people but I can't see how they'd be useful for anyone with a desktop or a laptop, and especially for those with both. So I'm just curious to hear from others that have found a place in their lives for a tablet - how do you use it? Do you find it replacing either desktop or laptop for you?
