Imho the gap between desktop and laptop is getting smaller. There are quite some laptops shipping with UDMA100 now. "dd if=/dev/ad0 of=/dev/null bs=4096" gives me 22 MB/s. I don't have a recent desktop so I don't know how this compares to recent desktop performance but I don't think it is bad. This combined with a 1800Mhz PIV and 256MB DDR memory makes it do buildworlds in 45 minutes.
