The classic scene is I think the only one that people can still rally around. It is unassailably Amiga. It has the most activity going on at this time, and unites both those seeking a retro 'fix' and those who realise that you don't really need a 12GHz septupal core Intel Core15-Ultra-Mega-Overheat to do a bit of word processing, artwork or use a spreadsheet. Projects like the MiniMig, Clone-A, the AROS Kickstart replacement, Motorollin's 3.9 ROM hack, lots of interesting projects that don't concern themselves with the tech race. Which is nice.
Here, Here! Well said. Sums up my sentiments about using the old hardware perfectly.
