Google's Matt Cutts shows us how fast JJ can load using an Intel X25-E Etreme Single-Level Cell (SLC) SDD. The X25-E has a 75 microsecond latency, and up to 250 MB/s read speeds, and 170 MB/s write speeds. From notebook power-on to Firefox launched and running Google, it was 23.0 seconds, with about 5.5 seconds being the notebook's BIOS. At 18 seconds it had a mouse pointer and at around 22 to 23 seconds Firefox was loaded with the Google page.
Even though it does not show up on Ubuntu.com home page, you can already download Ubuntu 9.04 See Ubuntu's 9.04 download page and of course, the download mirrors.
If you are looking for screenshots, see here (nothing has changes mostly).
