Droid > Texas Instruments

I've lost multiple scientific calculators and after my last one I couldn't justify buying another calculator to lose.  For my econ final and all my lab reports, I used my cell phone.  On my old phone, I couldn't do more complex functions...but DROID conquers all!  I recently tested CalcBuddy, Kreac Calculator and RealCalc.  Kreac Calculator is my favorite because it has the simplest design and I can easily enter exponents.  One less thing to carry around, one less thing to lose and one less thing to buy (again!).
