I had two different A500s, a B2000, an A600, an A1200 and an A4000T.
I hated the A600.
I tried to like it, I thought I would be able to get by with that keyboard but I couldn't.
That A600 lasted a few weeks. Then it was outta there!!
The first box Amiga I saw was the A1000 and I wanted that. I don't think a Kickstart disk would have got me down.
So yes, I think the worst one is the A600.
And probably the best all-rounder in terms of price vs performance is the A1200. If I ever get tired of lugging this A4kT around, I will go back to the A1200.
