I have been a Windows user my whole life, but I want a new computer now, and I am seriously contemplating getting a Mac. This is a big decision for me, and I have two major questions for this forum. First, will a Macintosh meet my computational needs, or would a PC be better? Second, should I get a MacBook Pro or plain old MacBook? About 90% of what I do on my computer is internet, email, and Microsoft Office. (Maybe more like 95%) I love Firefox and Thunderbird. Some people say that Safari on a Mac is not as good as Firefox on a PC, and that Firefox displays pages faster. Is this true? If I use Firefox in OS X, will it be faster than Safari, or is Firefox for OS X worse than Firefox for Windows? Having a fast and good internet browser is very important to me, because I will use it a lot. Also, how is Thunderbird on OS X? What do people think of the following programs on OS X: Microsoft Office, Adobe Photoshop, ChemDraw (ChemBioOffice), Mathematica, and Finale? I know that Photoshop used to be really slow on Macs, did they fix that? I think I want a MacBook Pro, but I am also looking at the MacBook. I like the bigger, 15.4" screen, and I think screen size is important for productivity and usability. I don't really need the extra ports or the video card, though. Which is more likely to get scratched, or dented, or dirty, the plastic MacBook or the aluminum Pro? I have some time to contemplate my decision while I wait for the MacBook Pro updates to come out. Thank you.
