Win7 for desktops and laptops, win8 for the newfangled bullshit hybrid tablet laptops they're making.
Windows 8 on a desktop or laptop is a stupid gimmick and Microsoft knows it. Sent from the new and improved space phone.
My Macbook needs the function modifier key but my iMac has the full keyboard with proper function keys. In any case the F11 shortcut only seems to work going from full screen to windowed. Once it's running windowed it may conflict with a normal system shortcut so it won't swap back to full screen for me. The other issue is Macs running OSX older than 10.6 can't use full screen at all. Even zooming your window can be touch and go. You can wind up with anything from scrambled graphics to a complete freeze. The safest option is to set the screen res in the profile so it opens to the size you want to run.
Speaking of MacBooks, just had a mechanical failure on my MacBook's hard drive so pretty much lost everything. Thankfully all my music and photos are on an external drive and I can probably re-download my Game of Thrones, Futurama, True Blood but that's really going to eat into my 200GB downloads for the month. Maybe this will teach me to do backups.
