Dennis,
I just equipped my 4 kids (Grades 7,8,11 and 12) plus my wife (back at college since this fall) with FIVE new calculators.
Guess what: They all decided for the TI-84 Plus Silver Edition:
Jana: Light Blue - This years Wal-Mart color: http://www.datamath.org/Graphing/TI-84PLUS_SE_WM08_BL.htm
Stefan: Orange - This years Office Depot color: http://www.datamath.org/Graphing/TI-84PLUS_SE_OD08_OR.htm
Manuel: Dark Blue - Last years Target color: http://www.datamath.org/Graphing/TI-84PLUS_SE_TBL.htm
Andreas: Dark Blue - This years Staples color: http://www.datamath.org/Graphing/TI-84PLUS_SE_ST08_BL.htm
And my wife Barbara choose one of the four pink shades - this years Staples color: http://www.datamath.org/Graphing/TI-84PLUS_SE_WMST08_PK.htm
You see, its is not about RPN vs non/RPN - it is about fashion!!
My daily calculators are still a TI-83 Plus SE in the Office and at home I use a Canon FC-43. Why? I always have to convert Millimeters and Grams of my calculators into inches and ounces for the Datamath Calculator Museum.
