I would certainly agree that if you need the redundancy and don't mind buying N disks to get N/2 disks of capacity then RAID10 is the answer. However in an environment where writes are quite rare and there isn't a big budget, I don't really see a problem with RAID5 as long as the limitations are known. RAID 5's level of redundancy is still infinitely better than not using a redundant RAID config at all. http://www.miracleas.com/BAARF/RAID5_versus_RAID10.txt linked from the above site does explain it well.
