You're incorrect on both the MS Office 2010 and Adobe suites
I have purchased the MS Office 2010 "Home & Student" which allows installation on three different machines simultaneously, one of which I then upgraded to Home & Business to get Outlook 2010, but I don't believe there is a pro version that does. BTW, Office 365 may allow 5 installs, but it's a lease you have to pay each year. Adobe allows you to install onto two machines as long as they are not both in use at the same time (read home PC or laptop as well as work PC) - you deactivate the first install while installing on the 2nd machine, then reactivate the first one.
