My brother that has autism has been having constant issues with his HP 500 series computer we bought him 2 years ago. SLOW as can be. WIFI won't work over the internet, etc. It has been blown away and fresh install of the O/S from the DISCS that came with it. It helped with the wifi issue, but still extremely slow. AMD A8-6410 processor just doesn't seem to perform well. I even have an SSD in this machine and it seems the machine can't handle the speed. So with that, is the IMAC a good choice for $999? Or should I just get him the MAC Mini upgraded model and he keeps his external samsung monitor? I've heard this version of the IMAC is slow. Thoughts and concerns, let me know.
