My Calculator is Finally Wearing Out

After 8.33 years of being awesome, my calculator is finally wearing out. I got my TI-83 Plus back in 7th grade, when my Algebra teacher told us we would need a graphing calculator to complete the work we would be assigned.  Having only used simple calculators previously, I thought paying $100 for a calculator was a bit crazy, but I was only in 7th grade at the time and had no idea how handy this guy would be.  Over the better part of a decade, we've solved equations using intersecting lines, explored trigonometric functions, integrated some gnarly expressions, and we've even tackled some stress and strain relationships using matrix calculations.  We've conquered many a late-night homework sesh and frightening exam.  The screen is starting to crack and leak, and sometimes the buttons are unresponsive.  All in all, it's been a pretty good run.  Thanks for those answers.
