We really do need a machine with graphics. If we could get a machine which had graphics and more memory that would be much more attractive to switch to. This also has implications on the kernel support (cc Bruce). > As for dropping thumb1 support that's probably fine too - although > technically (if someone really did want to keep thumb1 support alive) > I guess nothing prevents testing thumb1 binaries on an ARMv7 CPU? Just guessing but they might work in some cases an a v7 CPU but fail on older ones due to alignment constraints? Cheers, Richard
