Do I have to have a computer to utilize itunes match, or can i take advantage of this feature by just having a ipad and an iphone?

iTunes Match is a feature you use in iTunes on your computer.

I don't know if you want to use iCloud. iCloud and iTunes Match are two quite different things. If you don't have a computer to set up iTunes Match and store your music on your device with no backup, then you will lose everything should have a problem or need to transfer your music to another device.

If you plan to use an iDevice it would be a good idea to own a computer. iPads and iPhones are not replacements for the computer. They are adjuncts to the computer. Otherwise, get a laptop.

Here is the fun part. You should be ok, as long as you activate your match, while still have a computer and allow time to upload and match your whole library. Once your music is uploaded, you can use ipad only. Problems will come if at some point you need to troubleshoot, or will stop subscription. Your itunes match info will be lost, and without computer back up is dead to you.
