If you want apps to open fast, get it, with this caveat ... my 1TB fusion is fantastic for all software, but I have noticed that MS Word seems a tad sluggish compared to Photoshop, Illustrator, Firefox, Mail, etc. Keep in mind I do have 704 fonts active and when Word opens, it's the font reading that is stalling it. I measured ~4 seconds to fully open. In comparison Photoshop takes ~2 seconds with the same fonts active.
