A more unified computing environment: I love the simplicity of spreadsheets, the plotting of Matlab, the interactivity of SLIME, the pragmatism of bash scripting, the breadth of knowledge of Wolfram Alpha (and Wikipedia), so on and so forth, but I hate having to choose one environment. Julia is the closest thing I've found to what I have in mind.
To put it another way, I want exactly one tool that's truly the best way to answer all these questions: What's 2^25? If I drive X miles a year and pay $Y for gas (+$Z for premium) in car A, how much will I spend per month? What's the largest prime below 9000? What does some list of numbers "look" like? Is there any trend between US Presidential elections and the following Super Bowl?
