There are MAC version of Microsoft Office.
Though i believe most of us here is using OpenOffice or other opensource, which might have some formatting/layout issue with MS Office.

Hassle free, erm.. well yeah. Everything is quite simple with MAC OSX. You just need some time to get used to it.

Head to www.applemalaysia.com.my and locate premium sellers. IMHO, I prefer to buy from premium sellers as they know their stuff. The past 2 authorised sellers store I entered was not very good at Macs.

For me, I bought mine from MacStudio in LowYat Plaza. They have the best deal too

Also, since you stated in your other post that you travel a lot, why don't you consider getting a MB instead of a MBP? MBs are more than enough to do your office + house workload (word processing, presentations, watching movies, listening to songs etc)

Inevitable, im at the computer 10 hours per day, well a bit more than your four, maybe a lot more, and yes, eye fatigue..
1) No, even when you say simple errands like surfing the net (safari), or having a chat client on (Adium), just the fact that you are running parallels will be more than the reason you upgrade the ram. I'm running "simple" errands and at idle state, my mac consumes about 50% of my memory capacity.

2) Sims 2 will work in Windows XP, hence parallel.
