Maybe some people posting in here are classic 4.1 users..I know I am running it on a 4000

In reply to one of your comments my RTL8139 NIC does not work as it does in 3.9 so I bought a few of the 8029s from AmigaKit and the Internet Wizard had me on the network in just a few seconds. I do have a SB Pro but, due to lack of space in my 4000D, I don't have the room in her to install it.
Only issue I've seen with 4.1 is the error message I'm still seeing noted a couple of posts before this.
Other than that in an A4000 w/233MHz CSPPC and 128MB I am very happy with the OS. Appears to be miles ahead of 4.0 (I installed that once and took it off) - 4.1 is a keeper so far and is very usable. My hardware 'just worked' out the box and I was running a 1920x1080 desktop on a 32" LCD via DVI straight off the bat. Only installation problem I had was taken care of by HammerD and was basically me installing a Subway driver by accident during the Poseidon install for the Deneb.
Overall, I'm very happy with it. Personally, I wasn't expecting a discounted upgrade from 4.0 as the Amiga commercial software development landscape in my opinion is very different than that of the PC world. This stuff is sold in comparatively minuscule quantities and the developers that write this need supporting. I look at the cost as part upgrade cost and part the cost of making this sort of development still viable which I'm quite happy in paying.
