Hello! I am an avid user of the PC for the past 16 years, and finally I have decided to make the switch, so I just got a fresh MacBook a few hours ago. While it's a little tough trying to get used to it, I'm having a great time with it so far, but I do have a few questions to ask. 1. Is a fresh install of the OS a better idea to go with rather than going with the original installation? I took a look at the amount of space I have and already nearly half of the HDD space is full! Would creating a fresh install make it less space heavy? 2. What are some good (free) apps to go with the MacBook? 3. I'm planning on getting my RAM from perhaps an outside source, since getting it as an upgrade from the Mac Store was downright expensive, does anyone have any good sources to get some decent RAM? I'm planning on getting up to 1GB but if there's a cheap alternative for 2GB I'd love to hear about it. Thanks in advance, I'm looking forward to completely switching to the Mac Community.
