Another thing really bothers me is that I can't read USB sticks (and other devices) if a mate comes around and hes using Win, Lin or Mac. The USB Sticks will be recognized as super floppies and then they don't work without to be partioned and format on os2. There are lot of barriers using USB devices. This should be easier to change data between systems. Same problem for USB mp3 players, cameras, sd cards etc.pp. Generally the combination of USB support and files systems should be much better.
It occurs to me that the "large floppy" problem might be fixable by using a device filter (*.FLT) to detect the problem, and put the LVM stuff in front of the drive (but not on the drive), so that LVM will see what it wants, without messing with the drive itself. This would not let you use specific drive letters for the device, but it should work with the drive letter that gets automatically assigned.
I would also have to better font rendering
I need to ask what: What is wrong with it? I find font rendering to be excellent. It is never perfect (even with Windows, or Linux), because of the nature of the devices that render them. Pixels are of a fixed size, and there isn't much you can do about that, other than to use the settings that the device was designed to use. Most of the time, the visual problems are caused by using a VGA connection, where the device needs to convert the analogue VGA signals to digital. That never works quite right. DVI, on the other hand, always gets the dots lined up properly. There is still some mismatch where characters go around corners, because you can't use part of a dot. Printing has always had that problem because it has always used dots. High resolution is the best answer to those problems.
I dont know situation on cups I never - I used it
You, and everybody else who has a printer, should try CUPS, even if your printer is not supported. It seems that CUPS is the only hope that we have for future printer support. You don't have to actually use it, you can have multiple drivers installed for the same printer, so you can use the one that works, and see if you can get the CUPS driver to work. When more people try it, and report problems, there is a better chance that problems will get fixed, and it will support more printers in the future. From what I have seen, what gets supported depends a lot on what Apple decides to support, and there are problems when the printer manufacturer supplies a proprietary module to make it work (never supplied for OS/2, and we are not able to "port" them).
This seems to be problem of FF itself and not of the port
In fact, the current port (FF 24.8.1) is working well. It loads a little slower than the windows equivalent, but once it is operating, it seems to be about the same as on windows. I think it has not been optimized for performance, and still has some debug code in it. Of course, you are right that it is bloatware, and that is also true on all platforms. Older hardware will have problems, unless there is enough memory to keep it from swapping. Otherwise, it seems to be okay. If you are still using old hardware, you probably need to use an older Firefox, but that introduces the possibility that malware might do something bad. That is probably not as dangerous as on windows, but there is still an exposure, and some of the newest tricks may not work right.
Maybe we will need a new TCPIP stack for the next IP
IPv6 is a bit of a puzzle. It seems to already exist, on other platforms, but I have not, yet, seen anything use it (that could be because I use OS/2, and a router that has the option turned off). It appears that we will not have a problem, until something actually insists on using it, with no alternative. When that will happen, is anybodies guess. Meanwhile, that is another thing that is approaching the top of the list. I think we are safe, for a while, simply because there is so much old hardware, and software, out there that won't work with it.
