well my iBook g4 933mhz is a little heavy, is totally grubby (pearly white is a long lost memory) and the hitachi hard disk died recently (luckily several months ago i modded in a western digital 5400rpm drive so the iBook LIVES! and THRIVES!)
despite some drawbacks the iBook is a workhorse beyond its anticipated use by date. and no spyware, adware, malware, or other bollocks.
no pentium M pee cee laptop for me, with that fantabulous 915GM GMA9shite graphics power* and 4200rpm drives
but yeah there is room for improvement. May the MacBook bring such improvements. including FINALLY WIDESCREEN for heaven's sake.
*okay okay so the GMA900 might be faster than the mobility 9200 in the older iBooks......
