I am a switcher - picked up a G3 300Mhz iBook in mint condition about 6 months before MacOS X came on the market after being forced to endure Windoze for too many years. I have been using MacOS X since 10.0 on my G3 300Mhz iBook because 9.x was just too fragile for me after using Win9x for years (that say's alot considering what crap Win9x series was). I just love the design of this little iBook machine. Even though each iteration of X is getting a little better, I find that all the font smoothing, transparency & animations just *kills* it. I am one of those folks who went travelling on the road & never stopped - I use the iBook *heavily* whilst travelling on the road all year round to store and manipulate *a lot* of images amongst other things. I am not disposed to buy a new Mac laptop (much as i would like to!) because here in Oz we pay exorbitanat prices for them so the stagnating hardware platform is overpriced at present IMHO. Looking on the secondhand market for a replacement Mac Laptop what should I go for to see a real, tangible boost in performance as against a fractional increase a'la wintel?
