yep, get a g5. Id like, one, but my 4 year old G4/450 will do me for a bit yet.
Id only really want one for UT2K3 as my G4 doesnt really cut it for that but I really dont use my g4 much..
since i got an ibook 1 1/2 years ago, and now have just got my new 12" tibook which i use all the time as its just so much easier to sit in the front room with a laptop on my Habitat surfing table.
the tibook runs UT2K3 really well considering its specifically marked out as one not to use in the UT2K3 specs.
