Do you read faster or slower on a device like an iPad or Kindle, in comparison with a physical book? The overall answer, according to usability expert Jakob Nielsen, is about 5 to 10 percent slower (with the same comprehension of what was read). That's statistically significant, though not all that much slower. (We suspect it may have to do with years of familiarity with the form factor of the book.) More interesting was that on a 1 to 7 scale, users rated their satisfaction at 5.8 for the iPad, 5.7 for the Kindle, and 5.6 for the physical book, with the traditional PC trailing behind at only 3.6. follow link
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.

Jakob Nielsen Tests iPad and Kindle Reading Speeds
"More interesting was that on a 1 to 7 scale, users rated their satisfaction at 5.8 for the iPad, 5.7 for the Kindle, and 5.6 for the physical book, with the traditional PC trailing behind at only 3.6."
However, this is somewhat misleading. Those who read the original article will see that the sample size is quite small (27) and so 5.8, 5.7, and 5.6 for the ebooks and the real book is certainly a statistical tie. The writeup doesn't make clear whether the difference between those books and the PC was statistically significant or not.
