Okay, I'll bite: if you're using BB to do a crapload of stuff that most unis and instructors don't do, by all means, keep licensing it. Most of the people at my uni barely know how to do anything with it other than use it as a PowerPoint server. Sad, but true.
But if you're not using it for anything exotic, for the love of g*d, dump it and save yourself a boatload of money. I'm all for using the right tool for the right job, but I honestly know people who teach where I teach who say, well, they both suck, so let's suck equally with the thing that everybody's heard of and costs an obscene amount of money in a year in which our state is forcing state workers to take unpaid days off work every month.
Really sad.
And I see we've already had this conversation , so I'm really not arguing against you personally and your system if you are getting your money's worth. But, really, for unis using it as a PPT server... seriously bad use of money. And I swear that there are unfortunately alot of us out there doing just that.
