Well, in one view you see several types of information. Whether those are useful to you, matters on a case by case and is personal.

I sometimes, when connected to a public WiFi AP, consider it useful knowing my IP address.

Sometimes its very useful knowing which applications are using the most CPU time or RAM.

It might save you running other applets or panels.

And so on, and so on.

You don't have to (always) run it, and you can modify the config to your taste...

PS: I always had a SLC1000, and now also a N810..
