Okay, here's some hard data. Acer Aspire One ZG5 with an SSDPAMM0008G1 (cheap/slow) SSD, Fedora 13. Doing a standard yum update, measuring the yum cleanup phase while browsing with Firefox: Default extN: machine becomes completely unusable for minutes. btrfs with ssd_spread: machine functions normally, cleanup finishes in (often much) under 15 seconds. Regardless of what vmstat says, btrfs is clearly faster on this hardware.
