Hi all- First of all, this is my first post on MacRumors ( ) and I'm fairly new to Macs, so sorry if some of my questions seem a bit simple... Basically, I've switched to Macs since I was getting annoyed at my infected, diseased and dying PC, so I bought an eMac for £200, the best thing I ever did... I recently bought a G4 PowerBook 1.25ghz from eBay and was wondering what programs are essential, the 'must haves' when using a Mac. I hope to be editing video and doing some graphic design, but I've already got FC and PS... I was wondering if there are any drivers or media players which I won't be able to do without, ie Windows Media Player, Real etc, or whether I will need anything to help compatibility between my Mac and other websites, peripherals etc... Also, the PowerBook will come with 512mb RAM, but I was wondering if this is worth upgrading, and how much I can fit into it? I hope to buy Tiger soon, as well as more RAM if recommended, and I've heard that there is an Apple store in the Orlando Millenia mall, so my question is whether it will be cheaper to purchase Tiger and any RAM or other upgrades at the store when I'm in Florida in 6 weeks, or to use my English educational discount (University) at the online store? Sorry again if any of these questions seem blindingly obvious, but hey: I'm a newbie Thanks for any help!!!
