well lets see, the imac smoke iMacDV SE 500 mhz: slot load drive kinda finicky, one FW port dosnt work, but that could just be a faulty port, i dont use it too often so i dont know the problems
PBook pismo G3 500mhz: the apple logo is upside down when the lid is open, and light shines through the logo and the lcd if the screen is off and the lid is open. the drive releices to releice whatever drive you have in the media bays are too flimsy. no command key on right side of spacebar thats all i notice.
iBook twin usb Gen 1 500 mhz: scratches too easally ports make it feel that i am putting too much pressure on the USB plugs when i have the comp in my lap, i wish the powercord was on the left with the rest of the ports but i can see that this couldent be done. the magnetic latch broke on mine, it broke on the bottom where it latches, the peice of metal that holds the hook just broke in two and apple wont fix it (i havent really talked to them about it in full detal as that i dont have an afternoon to throw away by sitting on hold forever)little feet on bottom fall off and apple likes to charge you, but if you mention it with another problem they will toss the feet in free. the paint on the inside of the acrilic on the battery chips. my modem is busted too, but i dont use it.
iPod 10 gig G2: scratches on back, i wish it was brushed aluminum, edges too square, fixed on G3, buttons can get pushed if its in yer pocket the wrong way, fixed in G3.
DOSNT BOUNCE
and dosnt play well with others (mind of its own)
