With the Crafty chess engine test profile, the T61 was quite a bit faster than the System76 product.
The ThinkPad T61 also did better than the Bonobo Professional when it came to RAW image file to PPM image conversion using dcraw.
Our testing ended out with the System76 Bonobo Professional capturing one final first place finish when it came to the SQLite performance, where it trounced the Lenovo ThinkPad T61.
While the System76 Bonobo Professional notebook boasts a 1920 x 1200 display, an Intel Core 2 Quad Q9000 processor, and a NVIDIA GeForce GTX 280M graphics processor, this beast is power hungry and it is rather heavy and bulky. It would be miserable to carry this laptop around while traveling or even to and from the office on a daily basis. However, if the laptop will mostly be stationary, or a powerful yet portable system is necessary, there is the Bonobo Professional. When it comes to the performance of this laptop, we are certainly pleased with its graphics performance and with the overall system performance we were pleased with the results overall. The build quality of this notebook is also great and the features like eSATA connectivity, Firewire, a large keyboard, and web camera are all excellent too. Of course, with this notebook coming from System76, there is complete Ubuntu Linux support for this notebook. If you are looking at something lighter, cheaper, and to squeeze a bit more battery life out of the system, there is the Serval Professional that is also available through System76.
