I like the idea of a netbook and I don't think the weight would be that much of an issue. I can't see a tablet being terribly easy to use for actually entering text for a blog along with photos. Most of what I've read, including the link added by simplygib, seems to indicate tablets are mainly designed for browsing and not so much what I'd be intending to use it for. Of course with the usb and micro usb ports on some of the tablets you could add an external keyboard, but then wouldn't you end up being back up to the weight of a basic netbook? I'd gotten the impression that netbooks were not terribly common anymore because of tablet PCs becoming so much more common.
