Speaking strictly from design, they're fantastic. I love the look of 'em, and I really miss the look of their backlit keyboards. I adored the PowerBook G4s before them, so makes sense that I'd like a laptop 100% modeled after them. I'd love to get my hands on a functional early 2008 at some point to play around with something later than El Cap on one of these, but those are getting rare and commanding a premium.
I realize this is probably getting into rant territory at this point, but I cannot say enough good things about the keyboards in these machines. They're much heavier and softer than you get from a lot of modern laptop keyboards, which tend to be lighter and crisper. I enjoy the crispness of more modern keyboards, but there's something about the gentle soft keystrokes of this one that just does it for me. I use my late 2007 primarily for writing these days, and it performs beautifully for those needs.
On the downside it runs hot, it's limited to El Cap (and no, dosdude's patchers aren't an option here), and pretty much anything heavier than word processing sets the fans to roaring. Those flaws aside, it's a wonderful computer that I really enjoy using!
Below are some pics of mine, some comparing it to the first Unibody, a late 2008 15" for those that have never had the pleasure of using one of these old beasts
