I quite like Office 2010. There's not much difference between it and Office 2007, except for an improved ribbon interface, greater speed and a few new tricks. As for getting it by dodgy means, I wouldn't bother. Essentially, it has to be reactivated every 180 days by a Microsoft server so unless you have a good KMS activator, it can cause a few headaches. It is really cheap for students, so I agree with Sneaks on this one. I'd buy it.
However, if you're anywhere near as impoverished as I currently am (though I'm not currently having to re-use teabags), I do have a good version of Office 2010 that I use. I can upload it for you to download and install. :-)
