Extremely Happy with Cubase 7.5!!! PC Windows 7 x64 of course!!! 
+1
BEST UPDATE EVER!!!
Worked like a charm. I ordered the BOX version and let me tell you… Everything all settings, preference, key commands, ICONS, Color settings etc. went copied from 7.0.6 automatically.
I couldn’t been happier. And all talk about loading times? Never notice anything strange. Works perfect over here fast as usually. Load time of Cubase 7.5 seem even faster then 7.0.6? It takes about 10-15 sec.
I even loaded a old 7.0.6 project. Much faster load time then before or the same, about 20 sec. Medium size project about 4.8 GB RAM Kontakt 5, Omnisphere, Audio etc…178 tracks…Less CPU in use too on same project.
