380 V DC is the battery voltage on a PowerWare UPS... they have simply removed the DC2AC converter and operates on battery voltage... and most of the loss is from the DC2AC converter. A switching mode PSU needs DC so AC from the wall goes first to a rectifier and then to at HF generator (100KHz or more), then to a relativly small transformer (HF = small loss = high efficiency on a transformer), then again to a rectifier and then to some voltage regulators (+12V, -12V, +5V, -5V, +3.3V). It is littlt oversimplified maybe but this is the basic idea. The idea behind this is to get rid of a big, heavy and expensive (due to the price of copper) transformer. Your other idea 3x440 AC makes the initial rectifier very problematic. usually you just use 2 or 3 std. PSU's and connect them to different phases.

My ups need 40A @ 220V (single phase) and my power supplier denies me that...
My friends bought a Media PC (Windows Media Center) for their new 46" TFT TV... what they got was a 27m3 GameCube for their kids... That's what happened to the Media PC.
No sane adult couple with kids (kids age between 6 and 18 years) will buy a PC for their new widescrenn 40"+ HD TV... if they want to keep the TV for what they bought it for.

There are some rules in the financiaæ world thet requires proper documentetion of allmost everything. Now MS just said to the public that they do not have the proper documentation for the product they sell... so there may just be several large financial institutions (at least in the EU) that may not use MS software due to the now officcally known lack of documentation.

"OEM's can't go Linux yet and be taken seriously." Oh yes, they can. They just don't have the balls to do it. Just remember the "great" Windows support back in the 3.0 days. Getting a

That is correct. The problem right now is that patents hurt more than they help and therfore the whole idea is generally bad. If the system haven't been misused and foobared it would not have been bad.
