I'd love to see a better alternative to Excel geared more towards scientists. While it is true that R and python should be used for analysis, its often hard to escape a tool like Excel for data entry or browsing datasets. It would be nice if there was something out there that was faster and could handle larger datasets, and had features designed to help with data entry and browsing. I am envisioning something with double-entry data checking, enforcement of data types, and rules to check validity. Equally important would be the features it would lack - no tools to color or format text, no variable font sizes, no embedded images, etc.
