A few days ago, my new(secondhand) calculator came in the mail to add to my little collection.
The calculator has an issue turning on, but this seemed to be due to the operating system being corrupted. So my brother could with the help of Brandon Wilson bring it back to a working state.
The TI-84+ is in a decent state and will help me in my goal to be able to run *all* the files on Ticalc.org ;)
The usb feature is new to me, but it looks awesome. The only problem is that it still won't wok on a mac, but this is the fault of TI-Connect X. However that bug should be fixed, I think, in V4, which should come out in april, if I'm not mistaken.
