Fingerprints is a problem, but a more minor one. Pulling your hand off the more accurate touchpad is another one. Screen weight/balance is another one, you want a really stiff screen for touching, but not so stiff you can't easily move it. I'd say one of my biggest peeves is tap area sizes. Your fingers need much bigger areas to tap in accurately, so an efficient touch UI needs way more space for tap areas. But that space is wasted when you are using a mouse/touchpad cursor. I think Apples stance that the additional costs and impediments aren't worth the minor gains has been reasonable. But it's probably close. I wouldn't be shocked if they changed their minds on their next round of laptops.
