There are now four calculators in the 49 series of HP graphing calculators. These calculators all have both algebraic and RPN entry modes, and can perform numeric and symbolic calculations using the built-in CAS, which is an improved ALG48 and Erable combination from the HP-48 series.

The 49 series is often compared to the Texas Instruments' TI-89 series. Speed of calculation varies between the systems — generally the TI-89 series CAS (based on Texas Instruments' Derive engine) outperforms the HP-49G series CAS in areas such as simultaneous equation solving, integration and symbolic matrix manipulation; however, the 49 series is generally faster in other areas, such as 3D plot generation, series expansion and numeric matrix manipulation.

The 49 CAS has more tools to solve a wider array of problems than the TI-89 CAS, but this flexibility makes it more difficult to use and often slower on classroom book problems.

HP 49G

Released in August 1999, this calculator was the first HP unit to break from the more traditional subdued coloration. In addition to having a metallic blue color, the keyboard material was rubber and did not have the traditional HP calculator hinged keyboard feel. In addition, it lacked a large ENTER key which was seen by many as the defining sign of an HP calculator. These changes were disliked by many traditional HP calculator users.

The 49G incorporated many of the most powerful interface and mathematics tools available on the HP-48 series into the firmware of the new 49G, including the ability to easily decompile and compile both sysRPL and Saturn assembly code on the unit.

The 49G was the first HP calculator to use flash memory and have an upgradable ROM. In addition, it had a hard sliding case as opposed to the soft pouches supplied with the HP-48 series. The last officially supported ROM update for this calculator was 1.18, but several unofficial ROMs were released by the developers. The final ROM version was 1.19-6.

In 2003, the CAS source code of the 49G ROM was released under the LGPL. In addition, this release included an interactive geometry program and some commands to allow compatibility with certain programs written for the newer 49g+ calculator. Due to licensing restrictions, the recompiled ROM can not be redistributed.

Issues, bugs and criticism

The major criticisms of the 49G calculator dealt with the new rubber keyboard design and strange blue coloration. Users reported that some of the rubber keys could easily disconnect from the plastic structure. In addition, many felt that the 49G was based on outdated hardware that was surpassed by the TI-89's faster processor and higher resolution screen.
