TI-89 Titanium

For people who check facts
The TI-89 Titanium is a graphing calculator announced by the Texas Instruments company, positioned as a replacement for the popular (but now low-margin) TI-89.

The touted advantages of the TI-89 Titanum (over the TI-89) are: having roughly four times the available flash memory, a mini-USB port for connectivity to other (TI-89 Titanium) calculators, and some pre-loaded applications, such as ‘CellSheet’, a spreadsheet program also offered with other TI calculators.
