Software RAID performance is greatly reduced when layered on LVM.

Links to some concrete benchmarks/research/articles/documents showing this would be nice.

Updates to pros and cons

It seems by 2.6.37, all of LVMs current cons should be squashed. (Discard support, so SSDs can perform TRIM)

LVMs are still geared toward storage experts, though. The tools to properly manage LVMs are all TUI based. None of the features of LVMs, such as snapshots, are used in Desktop Fedora.

There still could be future problems if LVMs don't have support for Future Feature A and it takes 5 kernel releases to see support for Future Feature A.

What benefit does a Desktop Fedora user gain by having an LVM? Reduction of 1 MS-DOS MBR record? (swap and / combined)

The advent of GPT and Btrfs will make LVM obsolete - sorry. (Yes, GPT will become the default in 2011, motherboards will be coming with UEFI)
