4/5

My major issue with this gadget is that during performing many tasks at once, or sometimes even running tasks one after another it tends to lag or even omits some of the tasks it has been given. I've been troubleshooting, but didn't find an answer how to fix that. I'm using external add-ons (called Lists), but the Brain still sometimes ignores them for some reason. Plus, downloading new languages to the system takes so much time!

I like the community, though. Despite many bugs as Stupidity or problems with unwanted status updates (there's a patch called Poker Face, but it's a bit hard to acquire), users come up with their own solutions - some better, some worse. Usually there's no need to pay the specialist for servicing, you just got to ask your friends if they had the same issue, and there's a good chance they had and know how to fix it.
I thoroughly recommend using Resilience patch. It uses other plugins as Talk-to-a-friend, Hit-a-boxing-bag or Go-for-a-run, and apps (Critical Thinking) to fix minor problems, preventing The Brain from crashing. Definitely smooths user experience and allows quick adaptation to varying conditions. Needs uninstalling Stubborn app first, though.

Anyway, for now there are no better things around and I'll stick to using that one :)
