Hey, Yeah, I'd be another one of those hardcore Windows users that wants to convert to MAC thanks to Apple's viral advertising and genuinely interesting products, I bet you're pretty tired of all of these stories. But like any newbie, I need some questions answered by Apple Gurus before I take the leap of faith: 1. I'm from Australia, and I'm looking at the available MacBook models, and I'm wondering what the difference between a Combo Drive and a Super Drive is. I'm assuming a Super Drive is one that can both read and write, whilst a combo can't write? Can you upgrade from a Combo to a Super? 2. Money is a fairly tight issue for me, and I don't particularly need the 2.0Ghz model. I was wondering, what is more cheaper, purchasing the 1.8Ghz model (For $1748AU) and upgrade the RAM, HDD and Combodrive (Is that possible?) or buying the 2.0Ghz model ($2099AU)? Is 512MB of RAM enough for someone who browses the web (With a lot of tabs), IMs a lot, listens to a lot of music and runs Photoshop? 3. Is the RAM and HDD that you can replace from in a MAC a standard IDE/SATA drive, and any RAM that you can buy from stores, or is it a specialised one? 4. I've realised the keyboard of a MacBook is radically different from other ones in the market. Being a student, I need to type fast (I can type about 3 million words in a minute) and I was wondering how long it takes to adapt to that new style? Is it a difficult keyboard to use? 5. I've read that MAC has trouble reading NTFS file systems, and I want to back up my songs from my PC into the MacBook, would it do that comfortably, and vice versa? Thanks a ton guys! And sorry if I sound whiny, but y'know... such a transition isn't easy!
