I think the state of the computers is highly variable across properties. A couple of weeks ago I had great experiences with two Phoenix properties that had nice new touch screen Win8 all-in-ones and I had no problem using Office365 to edit and share some docs with colleagues. I've had plenty of other properties where I've been able to open GoogleDocs or O365 links and work on them. Sometimes when I need a larger screen or printer I actually appreciate these being available.
BTW, the comments about malware and public computers... if you're company doesn't have 2FA turned on for your access to company assets from public computers than that is the real problem. If it's on, there isn't much that a hacker could do with your login and password. But I do think it could be problematic signing into FF or other personal accounts that don't have 2FA enabled.
