Who, and why would people argue about you being knowledgeable?
I will let that one rest. There are a couple of people who seem to think I should just shut up, and go away. Oh well, I can ignore them.
There are a few things important to me, and I'd say it's Flash, Java, and multimedia support. My main PC has a Super-Multi bluray player. I have a feeling eCS won't support it(yet anyway). I know there is a VLC port, so I could run DVD media, and possibly some video formats. But X264 / avc? Not sure. I know VLC has everything, but if it doesn't support my graphics card's capabilities it probably won't be so easy. But, like I said, going to try it anyways. I don't like Mac OS, but I don't hate it either. Everyone has their own likes, preferences, and needs.
We have an almost "latest" FLASH, and JAVA. They use a lot of support that was created for the ODIN project (which is based on WINE, if you know about that). Both seem to have a few quirks, but that seems to be true in windows too.
To be honest, I don't know if BlueRay will work, or not. I think my CD/DVD drive is also BlueRay capable, but I don't think I have ever seen a BlueRay disk, never mind try to use one. DVDDAO is supposed to have support for BlueRay, but I don't know if it works. VLC is available, and it seems to work pretty well. I am also not too sure about X264. I think there is a program to do that, but I have never tried it. I also don't know about avc. We do have FFMPEG which seems to do a credible job of format conversion, but doesn't support everything. The biggest "problem" seems to be with Microsoft proprietary codecs. They just aren't available for non MS operating systems.
Graphics card... Well, it depends on exactly what it is, but my bet would be that it is too new to be supported by an accelerated driver (read SNAP). That doesn't mean that it won't do a reasonable job, in a lot of cases. There are two main video drivers. One is called SNAP (was SDD - Scietech Display Doctor - at one time), but development on that stopped a few years ago. It will support many newer cards, but only in VESA 2 mode, which is pretty slow. There is also PANORAMA, which also works in VESA 2 mode, but it has an added buffer that improves performance. Now, I hear that Mensys has acquired the OS/2 code for SNAP. Apparently, nothing has been done with it, yet, so it is difficult to know what, if anything, will come from that.
You should be aware, that eCS 2.2 beta is due to be released "soon". "Soon", in the past has meant anything up to two years. I think they (Mensys) are trying to do better, but most eCS users want it done right, rather than quickly. It is a difficult job, with one or two guys doing most of the coordination, and not many more doing the work. If you jump in with eCS 2.1, a lot of the newer stuff will be missing. You should also be aware, that eCS is cheaper, if you already own a copy of OS/2 warp4, or later. Sometimes they become available on places like e-Bay. I haven't checked prices for a long time, so a little research may be in order. You can also go to
http://www.ecomstation.com/ where you can order a free demo CD (electronic delivery). It is currently also a beta version, and it does have a few problems, but they may actually be fixed by now (or "soon"). It will NOT allow access to your real disk, and it has a few other restrictions that make it useless for anything but getting a bit of a feel for eCS. Depending on your system, it may work well, or it may be impossible to make it work. It should work in the latest VBox though.
BTW, I should mention that I have no connection to Mensys, other than as a satisfied customer. I did work for IBM, as a Customer Service Specialist, large systems, but retired (at a young age) in 1992. I have used OS/2 since version 2.0.
