Backlit calculators with list-based stats

[Chasfield]

The original Casio fx-9860G has no screen back-light but it does have an amazingly crisp LCD - the best of any calculator in my collection.

What about a Psion Workabout MX, or even some other pro. grade hand-held data gathering device that has a good numeric key board and decent connectivity? A back-light looks to be a standard feature of the Psion Workabout. Older models can be bought for little money and I think that they had the Psion spreadsheet built in. Also, you can whip up your own data gathering apps in OPL.
