Some other things to think about before buying a new computer (regardless of platform):
-Warranty on your new computer (1-year, but does the manufacturer extend it? In the case of most laptops, hardware on the laptop will break after 1 year; on a macbook pro, the display can cost as much as $700 if out of warranty);
-Compatibility with your colleagues: as for MS Office Mac 2008, it is 100 percent compatible with windows-counterparts in terms of file exchange; the main point here is that when exchanging files and attachments, you want to make sure the files translate from mac to pc or vice versa; in the case of MS Office Mac 2008, it does.
-Memory: on the issue of memory, check the requirements for the operating system, plus the software you intend to use most frequently; often, most people check one or the other, but don’t add both when factoring in running the app, the OS, and anything else (like a web browser or iTunes) simultaneously.
-What does your school use for email? Are they on a campus email system (like MS Exchange/Outlook)? Is there a way to get / check email when off-campus? In my case, I have a Mac, but whether a Mac or PC, no one can get email off campus unless they use a web browser (Firefox, Safari, etc.). If calendaring is critical (say the campus uses MS Exchange services), you’ll want to get MS Office Mac 2008 in most cases, to use the Mac equivalent of Outlook (Entourage).
-Cost of ownership over time: take time to research manufacturing process and workmanship on the model you intend to purchase. In my case, I opted to pay an extra $200 for a MacBook Pro (which is aluminum) versus the MacBook (white plastic), and in general, these things last years without fading or denting.
-Lastly, research any possible educational discounts; for example, Apple will provide a discount on their hardware to instructors, and also a discount on Apple-branded software. MS also discounts their Office products, and if you check with your IT department, the campus may participate in a MS campus agreement. At my college, the MS Office Mac ended up being $49 instead of $150, based on the campus agreement.
-P.S. If you do decide on a Mac, DO NOT upgrade the RAM or Hard Drive through Apple!! They mark up their hardware upgrades substantially (aka the “Apple” tax)...get the base model MacBook Pro (even the 13”) and use the savings to buy an external display (again, don’t buy Apple monitors unless you want to pay the Apple Tax!! There are several other manufacturers for displays-ViewSonic, Dell, just to name a few) that will get you more bang for your buck, and are compatible with Mac or PC.
As far as Mac is concerned, really try and research or test drive basic operation, because many uninitiated computer users switch over to Mac OS because of its ease-of-use and included iLife software (video editing/DVD burning/iPhoto/iWeb, etc.)
good luck with that; feel free to PM me if you have any other follow-up Qs.
