I currently own a Toshiba Pentium 4 2 GHz 15 inch notebook that is quite beefy and powerful. However, I only own it because I am overseas and having a desktop replacement notebook lends well to my lifestyle here. I currently live in Taiwan where space is something that is sparce. My stay here is about to end and I will go back to California in exactly one month. When I am back home, I will sell my notebook. It has suited my needs, but I would rather have one smaller notebook and a big powerhouse machine for development and gaming needs. The smaller notebook will be for word processing, tax use (TurboTax), occasional movie viewing, and doing these things on the run (wireless internet would also be nice to do). This is why I have considered the new iBook 12 inchers. My powerhouse machine will continue to be a x86 PC. The iBook will do mostly what I want it to do. If I ever get sick of MacOSX for whatever reason, I can stick Gentoo Linux on the machine. If I do purchase an iBook, I would select the 60 GB hard drive and then upgrade the RAM to the max via an upgrade from Crucial. However, I have some questions first: How is the battery life on the new iBooks (800/900)? How great of an impact does using the airport card have on the battery life? I live in a very yuppy area (in fact I live one city away from Apple headquarters), so taking the machine to a coffee shop and tapping away at a report or browsing the net should not be a less than 2 hour experience if possible. I cannot part without XViD/3iVX/DiVX support. Do these play on the iBook 800/900MHz models? Via MPlayerOSX? How well? How are the displays? How bright are they? Do they have good viewing angles? My Toshiba laptop had one of the best screens out on the market during the time I bought it at 500:1 contrast ratio, 25 ms refresh, very wide viewing angle, and 1600x1200 resolution. It also did not invert colors when viewing it from the side. Obviously, I don't expect the iBook to come anywhere near this, but how does it fare? Are there any other issues I should know about? Should I be considering the PowerBook 12 inch instead? Thank you all for taking your time to read this.
