I have 3 SR-52 and all have good keyboard; no bouncing. I don't know if it's the same techonlogy as the TI-58 series because 58 series keyboard is bouncing a lot but not the SR-52, SR-56, SR-50 too. Ti changes his scientific calculator quality a lot down since 10 years BUT their graphing calculators are very good quality; they know it need to resist teens hands in high school.. :-)
For the main subject, yes it's true, TI-89 titanium; not a lot of difference with the original one. Silver metal faceplate (humm, like the 33S) and more memory for flash apps.
look at the link there :

And a nice looking BAII+ metal edition too ;-)

BUT NOTHING NEW AS A SCIENTIFIC CALCULATOR, so ti don'T have any thing to propose to compete the HP-33S :-(
