When I got a 13" laptop I found that no more burden to carry around and it was *much* more versatile and powerful: the tablet never left the house after that.
I now have a blackberry playbook, and it's so much smaller (and to a lesser extent lighter) that I can chuck it in my bag without noticing it's there. So it tends to travel with me most days even if I probably won't need it, because it's no hassle to have around, and if I do find myself at a loose end I can pull it out and use it to listen to music, read ebooks, watch movies, play games - basically to kill time. Plus that smaller screen makes it easily managable in one hand, typing on it is easier as you can hold it by the bottom edge and "thumb-type" - OK, I'm getting a bit preachy now.
Basically, the 7" tablet fits into the "portable media device" niche much better than a larger 10" tablet (and therefore by extension than a netbook).
OTOH: the cheapo storage options tablet has a couple of downsides: firstly, it only has 256MB RAM, which I've read can be a significant detriment to Android 2.2+, and secondly, it has a quoted 4 hour battery life which (if my experience is anything to go by) will mean the battery lasts 4 hours regardless of what you're doing with the tablet (mine didn't save any power *at all* when in standby mode). So be aware that you're not going to be able to take it out with you and have it last all day - you'll need to turn it off when you're not using it.
If you're willing to spend a bit more, I think the Playbook is a great device. It's currently very short on app support, but it's meant to be getting an update that will allow it to run any Android app, and if/when that happens it will become (again, IMNSHO) just about the best tablet you can buy. PC World are currently doing an online-only special price of £169 on the 16GB version.
