comment Will Version 9 functions all work in Version 10?
Using SetSystemOptions["DataOptions" -> "ReturnQuantities" -> False] you can get back the old behaviour of DateDifference (trick from the 'Possible Issues' section).

Indeed. Are you going to report this to WRI?

comment Mathematica 10 Dataset doesn't format more than 4 columns?
What you see is similar to the output of the model fit functions and TimeSeries for instance. You get a summary object that symbolizes the data structure but is not meant to fully represent it visually. For formatting tables we have things like Grid or TableForm.

comment Plotting Time Series with call to Wolfram Alpha
Before stacking all the functions just try to get the W|A call to return something useful on its own. Financial data is obtained through Yahoo finance (well, at least FinancialData does that) and the results can be less than stable. Sometimes the same call that worked 5 minutes ago doesn't work now.

comment Menu bars on Palette windows don't work properly — any workarounds?
Bob thought he would be among the first to receive the new version, but I take it he still hasn't got his copy. So, see this as a semi jealous/hopeless/desparate/funny remark. Nothing to worry about. Sometimes you just take life too seriously :) BTW can't test right now. The iPad version of v10 hasn't arrived yet.

comment Menu commands on Palettes and other windows without menu bars?
BTW I like the new window/menu setup. It has several advantages: You can now switch between windows using the windows taskbar buttons, and the menu is never covered by another Mathematica window. You can still have a menu-free window by pressing F12.

comment Classify the classic tennis example
My current hypothesis is that the choice of Method is (partially) determined by the kind of platform you are on, and this through the determination of the PerformanceGoal. In my case, with that option on "Memory" it picks NaiveBayes, with the setting "Quality" RandomForest is chosen and with either "Speed" or "TrainingSpeed" I get NearestNeigbors. Are you on a super fast machine?
