I have a thing, with my Dean especially, but also her husband Chas, where occasionally I get all, "MINE!" at them.
This is shorthand, for: "Mine, in the sense that this friendship, this relationship, is going to continue, and will not go away, and I get to keep having you be a part of my life; however, this does not denote ownership or exclusive possession, you are allowed to have other friends and important relationships, e.g. to your spouse, whom I also love, and everything."
Oddly, it was only when I was confident enough to be all "... MINE!" at Dean that I stopped having jealousy issues of other friends. Because I stopped being worried that she'd replace me. Part of her is *mine* - other people get other parts, and that's fine, because the part that is mine is mine forever and no-one else can touch it so I have nothing to worry about.
Meanwhile: I haven't had a desktop for years, mostly because my living arrangements have been such that I'd have nowhere to put one. Widescreen laptops with full-size keyboards are, it must be noted, heavy as hell. I also have a netbook, which is tiny and light, but annoying and unsatisfying as a total desktop replacement.
