While CPU power differences could make a big issues, especially for games, I still say apple's fixed layout system is stronger. You load up a new screen with a call that specifies the layout file (called a XIB) on iPhone. You can then feasibly have different layouts for iPad and for 320x480 phones. I could easily support 5 of those. With a layout manager, you have to LOOK to see if it turned out well on the platforms (of which there are already 5-8 you care about, many times more than iphone). What android needs, is a gui builder.
