but he doesnt own one yet ! best bet is to ask grimspoon he's been using macs for years afaik
Um I think you will find I do.
I have a
15" Macbook Pro and I've had it for exactly a month now. I've also used a PC and Windows for the last 20 years and then decided to get a Mac for my Game Design work. I also would never go back to windows as I love my mac to pieces. Like Dan said your not going to get the same gaming experience, games that run on mac run awesomely on it, problem is alot of older games dont support Mac OS. There are ways around this, bootcamp, vmware, crossover etc.
For a functional working tool you cant beat it, it just works. User interface kicks windows down the stairs and takes its lunch money. It will take some time to get use to it but not long. We have 5 or so iMacs in the office all used by graphic/web designers.
What I love: Power, simplicity, mobility & the absolutely awesome App store. Good example; the Mac version of Office is called iWork, you can buy it online or at an Apple store for about £72 - £100 depending on where you shop. Buy the individual programs (pages(word), numbers (excel), keynote (powepoint)) directly from the app store for £14 a pop which works out to £30odd cheaper. Also the built in apps like Mail, calendar, iphoto, garage band are all top quality and I personally prefer iMail to Outlook or WindowsLive Mail any day of the week.
What I dont like is basically only some of the more glaring compatibility issues mostly with games, but I knew this going into it and as my Macbook Pro was never intended as my main gaming device there really isn't a downside for me. Some people will put the Price of Apple products in the hate section but I wouldn't, the MacBook pro is one of the most solidly built pieces of tech ever. Nothing on it feels cheap.
I suggest checking a few sites and comparing reviews, keeping inmind what you want to do and what you will need. There is also a really good Magazine (dunno if you get it in SA) called 'The Independent Guide to Mac' it has a tone of use fill info on most things Mac & its unbiased.
Edit: I hate safari, only opened it to download and install Chrome.
Edit2: you can also buy games like Civ V, Splinter Cell and a whole bunch of smaller games. directly from the App store. The Steam Mac OS App is brilliant and filtering to show only games that is Mac Compatible is easy as pie.
