I'm wondering about the performance, too.....
My dad needed a computer on his desk at the local Senior's Center, where he is their VP, but the lady who is President is a bit of a snit (total control freak, actually) about things on the desks in the office.
She outlined an area on his desk that was no larger than an LCD monitor, and said that's all he was allocated to use, because anything larger would be "ugly". SMH
I screwed a nicely cased Pi-B3+ onto the back of an LCD monitor, hooked it up and gave him a wireless keyboard and mouse combo that he can lock in his desk drawer, and he's been deliriously happy about it ever since. I'm sure the fact that the President is green around the gills over it, doesn't hurt, either.
I've used it a few times (maintenance tasks, for the most part) and do see a bit of a lack in performance with a few things, but I'm used to much more horse power out of a desktop system.
I'm now looking forward to swapping-out the old board for the new one, and seeing what sort of difference it makes in terms of performance.
