Tom's Hardware Guide posted a 14-page review on Ubuntu 10.04 LTS

It has been a little over two weeks since the final code for Ubuntu 10.04, codenamed Lucid Lynx hit the Internet. Last time, I had to wait a month before getting into 9.10, due to heinous errors, crippling bugs, and excruciatingly slow software repositories. Thankfully, none of this occurred with 10.04.

And it shouldn't. You see, Ubuntu 10.04 carries the LTS acronym, which stands for Long Term Support. Every six months, a new version of Ubuntu is released into the wild, but it's only once every two years that we get to see an LTS. The last LTS release was in April of 2008, when Ubuntu 8.04 Hardy Heron made its debut. These releases are especially important because this can make or break Ubuntu for OEM sales. Hardware partners, who could potentially sell systems with the OS pre-installed, will be looking to the LTS release as a benchmark for both quality and stability. Developers, too, will be paying close attention. Creating compatible software for Ubuntu should be much easier, and more likely to happen on the longer release cycle.
