Regarding the TripComputerButton, I'm a little surprised that this is performant in a table view! I'm guessing your buttons are fairly small (< 100x100)?
For this table, I also render the cells once and don't dequeue them, because I like to achieve the transparent, gradient effect for each table section, over the classic vertical lines of the grouped UITableView. https://www.dropbox.com/s/67xfol10c0kkqb2/TripComputerCellBa...
In the end, it is really great to have detailed knowledge of UIKit and CoreGraphics, so you save yourself time optimizing on the end, if you just know the right thing to do. And I think your comments about the accuracy of the blog's claims are righteous and a good addition. I envy your fundamental grasp of this stuff, and I try to keep learning, even as I fumble towards what I want.

Correct, the button is is about 190 x 30. It might make a difference that it is is in the tableHeaderView.
