As I mentioned in another post, I am now an avid user of Amplitude IOS, iRig pro, etc. I think they are a nice bang for the buck, and I have used them live and enjoyed the freedom and control I have with them. With the help of Audiobus, and some other apps such as Sample Tank, VocalLive, etc., it's now a viable option for performers and composers, too.
I think both solutions (computer and mobile) are important, and I'm guessing that IK Multimedia (which definitely has it's faults, too) is betting their investment on a burgeoning market--this is a business decision that not everyone (e.g. Larry) will be happy with, and I totally understand that position, too. Hopefully the company will use whatever profits they see from the increased investment in IOS, etc., to also add and enhance their PC/MAC products, which I also have used (though not as much anymore--sigh).
