Well after a long time I'm considering making the switch (from Windows to OS X, that is) - at least for a notebook. I've had some experience with a hacked version of OS X I installed on an old Sony VAIO computer, and I've had past experience with the official operating system as well, although I will admit I don't know everything about it. That being said, I'm considering buying a MacBook for school (and for entertainment on the side, I suppose). Foremost I'm a Windows guy, but Vista pisses me off to no end, and I'm generally getting tired of the Windows experience (I've been enduring OS after OS since 3.1x). My Windows Dell will certainly remain my workhorse: I'm a web developer, avid Photoshop user, etc, so my quad core is obviously going to be where I do that sort of thing. The bulk of stuff I would be using the MacBook for (in terms of school) would be typing essays (I'll buy the Mac version of Office), email/calendar/organizational stuff over MobileMe, doing research on the internet, and maybe making presentations with either PowerPoint or Keynotes. However, I'm beginning to think that for school it would make more sense to have a laptop that I don't have to constantly mess around with, where I can just get my work done without having to constantly babysit the OS (which I would not want to on a small screen/on a trackpad. Also, I've been looking into developing web apps for my iPhone, and I'd like to take that to the next level by using the SDK, which is another reason I'd like to make the switch to Leopard. Other reasons are the wireless connectivity of the MacBooks, and the fact that it will easily sync to my iPhone over MobileMe (although of course this could be said of any laptop). Anyway, I'm thinking about making the switch, but I need to be assured that the MacBook is going to play nice with my Dell if I ever need to access files on one computer from the other. Another issue is battery life. It seems to me that Leopard ought to be more friendly on system resources and in turn battery life, but that might just be me falling for the attractiveness of the GUI. I've read you can expect 4.5 hours of battery. Is this true? How do you guys find your MacBook's are on power? Lastly, I'm leaning towards the MacBook (vs the Pro) because of its portability. The 13.3 inch appeals to me because I can just throw it in my backpack and go, and not have to worry about lugging around a big 17 inch beast. Preferably, I'd like to not have to have it plugged in all the time: could you really get through a whole school day without plugging it in to charge it? How are "normal" operations (like the ones I listed above) going to affect the battery's life/integrity. I've used a lot of laptops that just don't last after a while. So, having taken all of that into consideration, am I ready for a MacBook? Thoughts/incites appreciated. Thanks!
