iStat Pro

iStat Pro is basically a different view of what you can get from the Activity Monitor utility app. Includes some temperature readings. I was thinking iStat Pro would be nice to check network speeds. I did some tests on my network speeds last year and did the stopwatch method. iStat Pro/Activity Monitor seems like a better way to go for that.
