You just admitted you can do these things on other cfw. The only difference is with cobra you don't need a backup manager. So you're saying it's worth having a dongle that shaves off a few seconds when you have something that can do it for free with a few extra seconds more?
That doesn't sound like a great investment, Do you know how long it takes to launch a homebrew app? I know you're trying to justify your purchase but it's not a godsend... once opencobra comes out there's litterally nothing but shaving a few seconds off to what you can already do on current cfw.
