Sure is.
I look at it this way, I've already played with the BeOS back in the mid/late 90's (on a 604 based PPC mac clone no less) Not really charting new territory for my self there. BeBox is an interesting piece, but it's not all that hot specs wise, really kind of limited and large, plus most development for Be is intel.
linux on the other hand, I have no experience with, nor Sun, NeXT or the Alpha computers. Those offer much more interest for me, to learn something new. I'm more interested in the experience, rather than the collecting side of things, not to say I don't collect at all. This is why my 'collection' includes just a Powerbook 180 and an Apple IIc. Neither take up much space and if I didn't use them semi regularly, I'd probably part with those as well.
