As a guy with too many U2s in the garage, I agree - but an Ultra 2 has a few nice things going for it:
It can accomodate up to 2 Gigs of RAM (U5/U10 can only take 1 Gig).
It has built-in SCSI for better performance (SCSI can be added to U5/U10 with a $25-40 add-in PCI card & drive).
Dual CPUs - as noted, may not be that big a win for single-user desktop, but an Ultra 2 with dual 300 MHz CPUs, each with 2 Meg cache may actually be cheaper than a 440 MHz, 2 Meg cache CPU upgrade for an Ultra 5/10.
HD15 (VGA) video connector on the U5/U10, don't need a Sun monitor/adapter like on a TGX/Creator/Elite framebuffer.
You can make a U5/10 very nice, if you have all the bits (U10 is best, as you can add a vastly upgraded video framebuffer, like an Elite 3D-6m, have easy room for dual SCSI HDs, a PCI SCSI card, and even another 1 or 4 port PCI ethernet card, depending on application and need...

I'm going to try an add-in SATA controller, and have an Ultra 5/10 boot off the IDE and use the SATA for storage - could be interesting...
