everyday computing? i would say yes, as i usualy "compute" on my amigas everyday or so... but then i don't earn money off my amigas, so in that case, no.
there is a certain element of "cos i can" but then on the otherhand, its amusing, interesting to learn how capable such a machine, with web browsers, APDF, flash players, blah blah blah, can actaully be in a modern world.
work is wintel/solaris-sparc, home is wintel/solaris-x86...
but i'm getting it together with learning C on amiga, so hey, you never know... :-D
at the moment it's a hobbie. but it shares my time with my other half, my DJ stuff, my car stuff, my PC gaming, socializing, and family stuff... so its a slow process i can't dedicate the time i could when i was younger, but i still enjoy it... even when the hard disk dissappears! ;-)
but i'm 100percent with everyone else, sentimentality, and this is my chance to own/use the hardware i drooled of owning when i were a lad :-D
