The keyboard that followed was a wireless keyboard and mouse combination that was hit or miss when I was playing games. There was a clear delay when I was typing quickly as well which was not a real issue, but it was an annoyance. Also, it was not a fully ergonomic keyboard (despite its title) and was still producing hand cramps. I was glad to see that one go.
For the most part, I like my current keyboard which I've had for about a decade. It's corded, so I haven't had any latency issues, and its ergonomic setup and wrist padding (although not as nice as the old Logitech one) is better than the one I had just before. Unfortunately, the keys are a bit loud; I've been much more aware of this when I am typing while I am unmuted in a class meeting. Several of my function keys no longer work, which is not much of an issue except when playing StarCraft II. Lastly, the lettering on a handful of keys are completely worn off; this is not much of an issue for me (in fact, I hardly notice, but Janelle mentioned it when she used my computer recently).
I would like to get a nice, new keyboard in the near future. The Logitech K860 has caught my eye and topped a few review columns I've looked at, but a price of $130 makes it seem like quite the luxury. The Microsoft Sculpt is $30 less and also has a nice rating, but I don't know about the separate number pad; I'm afraid I might lose it somehow. Both are wireless, but I think that latency is not an issue with these two.
I'm glad my current keyboard is not sentient, considering that I am using it to type a post about replacing it.
