from 1999-2005 believe it or not, I used an A1200T/060/PPC + PicIV + XSurf for everything. Web browsing was very fast, fastest I've used on Amiga (both IBrowse and Voyager, registered), Miami DX. Web is a different animal today, not sure how that system would still hold up, but at the time did all online banking and various transactions.
System was on a heavily patched 3.1 with various startup, everything using FastRAM except AGA screens on the other monitor + blizkick, tweaked memory, etc.
Sorta sorry I sold it all, but it was a massively hacked tower with CD Rom / Zip, many drives.
