Well, I'm more of a notebook man ...
Here's my bunch of early Intels, that do all more or less serve as daily drivers and do most of the work, that need to be done (though PPC do also take their part ...)
(In addition there is one stationary workhorse - a 15" MBP from 2012, that does all the heavy batch-Scan&OCR jobs in combination with DEVONthink.)
As for the early MacBookPro I especially like the option of having USB3.0 via PCExpressCard for fast CCC-clone-backups. Some MBP run ElCapitan, some run patched Mojave and Mojave will be the last macOS I'm gonna use for now, especially to keep 32-bit applications working. (BTW many thanks to
@dosdude1 for his patches!).
VMware Fusion 8 is great to run Win2k up to Win7 (and 10 on the 2012 MBP).
Four white iMac with Lion serve as a TerminalClient for RDP-connections with my office server.
The Mac mini is our media-center for streaming video at home (mainly in max. SD-quality).
Unfortunately the option of DVBT1 and eyeTV-recordings is gone ... One side-effect of tinkering with Macs: I was happy to successfully change the defective mainboard of our flat-TV, so it will hopefully serve us another few years "until the real thing comes along" ...
PS: great to have this Early-intel Forum now - many thanks to the editors and to all the PPC-Forum-members who stood in for the idea! 😊
