Sexy little (well medium i guess) device. As a software developer though I cannot see it replacing my laptop (currently a msi u123). I don’t see writing code on a ipad.
Also, it would not be replacing my phone. I guess we will be able to use skype (or skype-like services) on the 3G models. But still, the form factor of the iPad does not make for a convenient phone.

I recently found myself considering moving one of our servers to the Rackspace Cloud. I needed to get an estimate of the cost for bandwidth usage.
I remembered I had installed vnstat on that server when it was deployed.  This made the bandwidth calculation completely simple:

Just have vnstat give me the bandwidth sliced by Month:
$ vnstat -m

eth0 / monthly

month rx | tx | total

The install of vnstat on Ubuntu can be done with apt-get:
sudo apt-get install vnstat
Remember, once installed to initiate you vnstat DB.  Just execute vnstat and it will tell you how.   vnstat -u -i eth0 in my case

Then check the man page for the command to see all the different ways you will be able to slice and dice your network data
