Holy cow, this must be an april fool hoax! Dude, the rack is the reason why I love .. Reason! It makes it stand out from other DAWs, it offers a totally different workflow. There are buttons, knobs, faders and cables to play with - it's a real man's toy!
If Reason had no rack, but just a boring and abstract GUI, what would be the difference between it and *insert any 08/15 DAW here* ? Noooo, if you don't like the rack, shush! - go play with Cubase or whatever other boring tool you can find. Reason is harder than hardware! Hail to the rack!
