#2Good job, IBM. You may actually be ahead of other tech companies for once, although Google seems to be breathing down your neck in this area. Others seem to be at least a generation or two behind.
One other thing to note is that until recently it was believed that 50-qubit quantum computer would achieve "quantum supremacy". However, IBM itself has shown that we can simulate 56-qubits on a classical supercomputer.

Now let's see who gets to the 100-qubit quantum computer first and achieves quantum supremacy.
Going by recent developments, quantum computers seem to be following a "Moore's Law" of sorts, where their number of qubits pretty much double every two years. We need a few more generations to be sure of this, but it does look like this is the rate at which they are going to evolve.
D-Wave, which isn't a universal quantum computer, has in fact been evolving at 2-4x every 2 years (closer to 2x for last few generations).
This is exciting because unlike classical computers, quantum computers increase their performance by much more than 2x if their number of qubits double every 2 years.

#3I look forward to supercool (no pun intended) qSeries mainframes and whatever wild OSs they'll run.
Right now, it looks like it's a batch processing like thing, with a single problem using the machine at any given time with long setup/teardown times.

Very exciting, agree - although important to mention:

...for particular tasks.

#5IBM also plans to offer a 20-qubit hosted service this year.

Some of those tasks are transformative!

#7At what point do we no longer trust public key cryptography (RSA)? Where's the break point?

It's interesting to imagine what connected planet with no reliable encryption would be like.
Although I guess we can always fall back on one-time pads.

Quantum computers don't break all encryption. There's no risk of that, fortunately.

IBM Research is and always has been an industrial research powerhouse. I doubt you could name a company that has contributed so much to so many different fields over the past few decades (Bell Labs is the universal exception).
From [1]:
"IBM Research's numerous contributions to physical and computer sciences include the Scanning Tunneling Microscope and high temperature superconductivity, both of which were awarded the Nobel Prize. IBM Research was behind the inventions of the SABRE travel reservation system, the technology of laser eye surgery, magnetic storage, the relational database, UPC barcodes and Watson, the question-answering computing system that won a match against human champions on the Jeopardy! television quiz show."
