I'm sure everyone knows how much of an expense Microsoft Office can be these days. If you don't get it pre-installed on your computer you have to shell out that extra cash to buy separately; either way you end up only really using a couple of the programs. That's just what happens because you can’t customize, but in 2013 this is a thing of the past. You now have the option of renting just what you need going month by month for $10.00 a month or $100 for a year upfront.
Another new feature is that the whole suite can be installed on 5 devices (2013 on Windows; 2011 on MAC) and all your files will be synced as you work. Subscriptions also include any future versions of the suites. So no more dealing with discs that get dusty in your drawer and worrying if you lost the key.
