I think the most interesting thing about this release is the use of OpenCL.

With more and more popular applications using GPGPU techniques it's possible that normal users will start noticing the difference soon.

What I'd really like to see is benchmarks between LO 4.2, MSO 2013 and Office 365. Maybe AOO 4.0.1 as well. Benchmark some serious spreadsheets, the sort that take hours to run. I don't expect LO to win, but I do expect the results will be interesting and give areas to improve upon now they've got the Calc data structures sorted out.
