As far as newest goes, I would say the new addition to the TI Nspire series, which is the cx cas. Exactly like the cx, except it has cas (computing algibraic system). Don't quote me on the abreviation but its something to that degree. Anyway it came out late in 2011 and is flargging amazing... It will do everything you will ever need to do and more, you will be at an advantage with this calculator well into a masters and maybe even a phd in mathematics.
the newest phone invented is the i phone 5
