Richard,
welcome to the church of Apple. Here you will find you can do all that you wish without fear of retribution from the Cult of MS
Yes I just bought a whitebook about 2 months ago and it's free from all the previous problems. One word though on office. You will need to install WinXP first on either the boot camp or Parallels or VMWare software. If you want to run windows at the same time as your Mac OS, you'll have to use Parallels or VMWare. If you dont care and can do without then you can install windows on the bootcamp partition and boot to it when needed.
But I suspect you're asking because you want to use office but you dont want to install windows. If that's correct, then the only option for you to do is to buy the new version of MS office for the mac. Yes. MS makes Office for the mac. Amazing stuff actually since the first version of office was made FOR the Mac.. not the PC. So you'll have to decide for yourself what you'd like to do.
Version 1:
Use bootcamp and install xp then install office and boot to it when needed.
Version 2
Use Parallels OR VM and install windows xp and then install office then use it when ever needed
Version 3
Buy Office for the Mac.
Seems pretty simple. There are things to consider such as do you have a windows xp cd and key code to install... are you comfortable installling windows, antispyware, antivirus....
Or would you like to just sell all your windows software via craigslist and use the money to buy Mac versions? See if you're only using windows for office.. its usually better to just by the mac version. But if there's other things you're doing in windows like games, autocad... creating nice virus' to share with your friends.. then you'll need to be running windows and need all that goes with it.
Let me know if you've got any questions.
