"Just as some vague general advice: high-power or "desktop replacement" laptops tend not to have much battery life. They're also very expensive. "
Yup, they are expensive. The one I am looking at would be about $2500.00. It would be good for most games, of course, I only really play Civilization and GT5. I have recently purchased one for my kid and my wife. They are really well built, not like the other flimsy Dell laptops. The dual power packs is a pain in the ass, but not always needed.
If I can create two virtual PC's, and 32 Bit Windows XP and a 32 Bit Windows 7, I would be happy.
By sharing drives, I meant like a download folder, or downloaded software folder. Of course I can do that with a external USB thumb drive or hard drive. I have tons of free or purchased utilities, that I would install in all three operating systems. Having them all in a common folder would be easier. Plus, getting a fresh XP installation on-line for downloading is a real pain in the ass. In fact, I probably wouldn't do it. I would just put in a fresh SP3 installation, get the needed instrument software working and not do anything else with it. I am sure if I copy something from a Windows XP screen (i.e., a screen shot) and then go to my Windows 10 screen edited a word document, I could paste it in? If not, I have to past it in Paint in XP and save it to a thumb drive and then insert that file in the Windows 10 word.
I asked these silly things because I have zero experience with virtual machines. It is VERY important, that until I migrate some of my utilities and database (VBA) programs to Windows 10, that I can have these virtual machines access RS232 port (USB/RS232, I guess as I don't think there is a docking station for the Alienware machine).
If I can use this super laptop for work, I would use those instead of my aging M6600 systems, and I could write it off as a business expense too (which quite frankly I would use it for business much more than playing civilization and GTA5 as I never seem to have play time anymore now that I am on my own).
