Well the default here is more "Je ne comprend pas!". At least that is the quintessential reaction of the French according to urban legend.

Well, that is because that is what you are supposed to say in that case (also the Dutch version). There is no equivalent for "Bless you" in this context.

Somewhat :) But Medion sells here in those stores too, and their manuals are usually translated :-)

Yeah, but why pay the idiot tax to run an emulator ?

It happens. I had a pendant for PPC Mac Mini's for a while. They had superior standby behaviour earlier than the rest, and still could double as funky *nix workstation.

Similarly some old friends preferred the rather more expensive Apple Gestalts (afaik Apple called it that in the US too in datasheets, mostly just the specific case incarnation with different inner workings), just because they took insane amount of RAMs, and could be upgraded in later life. With SDRAM however RAM prices bottomed out for the first time, and that was pretty much the end of that philosophy, from then on per unit, new RAM would be cheaper than old RAM.

The next FPC version eliminates Watcom tools. (maybe not yet for win3.1x native though). Generating 16-bits dos apps on 64-bits *nix without external tools is now viable.

I never compiled p7zip :-)

Since 2008, nobody likes trampolines since they require writable stack. Most 64-bit targets were fairly quick to require that also(since they had no legacy software)

Well, the writing has been on the wall for a long time. Pity that they never did the reboot that Frank was talking about( generating C, more FB cgen style). Even though it wasn't my cup of tea, I was somewhat curious to see how it would turn out in practice.

From the website, it looks superficial, very basic. Wouldn't be surprised if FPC's ISO mode was more compatible.
