To play devil's advocate, all file systems will, to a greater or lesser degree, suffer from fragmentation. Ext3 will take a very long time for desktop use to produce performance reducing fragmentation, if at all. But even if you were running a server, say mail or news, that creates/deletes many many small files and produces some fragmentation, there still is no true tool to defragment an ext3 file system. In other words, yes, there is the possibility of a little bit of fragmentation, nothing you can do about it, don't worry about it, on a desktop you won't notice. Servers that constantly create/delete many many small files generally use other filesystem types geared toward that kind of use.
Ext4, still considered 'testing' for ubuntu, is supposed to have a defrag tool, though I've never used it (neither ext4 or the defrag tool).

P.S. Why aren't 'filesystem' and 'defragment' in my spell check dictionary?
