Nina vs. ARGH: Hardcover or Paperback?

So I was going to work a few days ago and I wanted to bring my current read with me.  However, my hardcover copy of Her Fearful Symmetry is a bit on the big and heavy size and it occupied a bigger space in my bag - and I even had to fit in a water bottle, my mini-first aid kit, and other stuff you'd be surprised to see in my bag.

I've always been excited about having hardcover copies of a book that I like, which is actually what made me get Her Fearful Symmetry in the first place:  It's hardcover and it's from the used bookshop which made it cost about less than 80 percent its original price.  I also have other hardbacks and I like the aesthetics but once you get down to convenience, paperbacks rule.

Discussing my dilemma with ARGH, he was very much in favor of hardcover books.  And his solution to my bag problem?  Get a bigger bag - a suitcase, perhaps?

I think I prefer paperbacks because:

1. They save more room in my bookshelf - more space for other books!
2. Which also helps me save more room in basically everywhere else that I stash them, especially in my bag.
3. They are easier to lug around since they are more lightweight.
4. They are easier to cover (see New Book Ritual).
5. They are cheaper.
6. They are cheaper.
7. They are cheaper.

I think I could go on and on and all my reasons would all translate to 'They are cheaper.'

On the other hand, ARGH is willing to get me a bigger bag just so I would get more hardcover books because:

1. Because hardcover books are more expensive, they are also worth more than paperback.
2. Authors and publishers alike make more money from hardbacks than paperbacks.
3. Hardcover books have more durable book covers.  And their spines do not crack.
4. Most books usually debut in hardbound versions.
5. Hardcover books have better quality pages and the dust jackets look amazing.
6. Aesthetically speaking, they look better than their paper counterparts.

And the discussion begins!  Which side are you on?  Are you pro-paperback or hardcover fanatic?
