How does spending between 300 and 800 for an Areca 8 port pay out when you
can get a P410 for less than 100?  Are they 3--8 times faster, 3--8 times
easier to replace, 3--8 times more reliable, 3--8 times easier to use,
3--8 times more durable, 3--8 times more energy efficient?  What is it that
makes them worthwhile?

It´s much easier to click the wrong button in a GUI than it is to enter the
wrong command in a cli.  If the cli is poor, the gui may seem much better ---
I have a switch like that and I´m pissed that the cli is so bad.  Unfortunately,
there aren´t any decent 1GB switches with at least 24 ports that are fanless :(

And how do you automate a gui?  That´s way easier to do with a cli.
