Here we go... An IBM R50e with 512MB of RAM and an 80GB Hard Disk. Processor is a Pentium M 1.8GHz. The only depressing thing about it that I failed to realize is that the maximum resolution is only 1026 X 768. I wanted something with a higher resolution but it slipped my mind.
Mobility Radeon 9200 32mb
40GB 7200RPM drive (I added this myself)
DVDrom/CDRW (called "combo drive" by Apple)
802.11g wireless (called Airport Extreme)
It goes about 4 to 4.5 hours on a charge, and is actually good enough to play Halo at 640x480 with settings reduced. My primary use for it is portability and 2D tasks. I have Office 2004 installed, so work compatibility isn't an issue on it, since my company runs very few things outside of MS office. The fan inside is basically silent, as about the only thing I hear is the hard drive. I'm not sure if the 7200rpm drive is a good idea, but I don't have a 5400rpm drive around instead. Oh well, it has a vent.
What I like most about OSX 10.4 (Tiger) is how fast it finds hotspots and connects to them. Just today, I went to someone's house for the first time. I had the google map available in safari already for reference. When I got close, I flipped open the iBook to bring it out of sleep, only to see that it had found 3 available wireless networks in the area already! It can connect to any one of them in 3-4 seconds--though I wouldn't know anything about doing something like that...
its not doing too good after my sister managed to stand on it and the monitor keeps just going white! i think it might just be the connector to the motherboard as when you hit it it comes back on so i'll have to strip it and if i get no where then its time for a new one (not sure if thats good or bad )
HP NC6000 its a 1.5Ghz Banias, 512MB, 40GB 8MB Fujitsu ,14" XGA, MR9600 (64bit) and now Ricoh DVD-RW equiped lappy (took some ingenuity to get it to fit into the Multibay, but it was well worth it, becouse HP wanted $350 for LG DVD-RW)
