I have an original model B with 256mb ram that still runs as my personal web and Mumble [VoIP] sever!
My daughter has a model 2B that she plays with, I might considering replacing it with the 3B+ as half the time she uses it for playing music via you tube and that can get laggy at times.... but to be fair, that was not an original use case when getting her the Pi.
I also have a couple Pi B+ setup as cameras, but if I was doing that project now I would get 3B or 3B+ for the integrated WiFi and avoid running Ethernet cables.
Preferably added together
Then I go to bed so I could wake up at 5:30 am and walk to school. Five miles away through the snow, uphill each way.
You had it easy. We had to crawl 10 miles each way through the snow over broken glass on our knees, dodging mortar rounds and horny priests.
Broken glass?
We had to walk on our hands 20 miles each way over sharp volcanic rock, and could only dream of piles of snow, since it was still hot!
Always draw your curves, then plot your reading.
