Depends on where you get your cables and what quality you want. The major Android phone makers sell them for about $20. With portable devices I feel that smaller is better. Smaller of course requires an absolute minimum of physical connectors, and requires using the most modern connectors. Apple does very well with this. I'd rather have to bring a cable in those rare times I need one than have a huge bulky device because they decided to throw in all sorts of connectors.
In those cases where you know that you’ll need to connect your ipad to a tv, I presume the apple and the android is about the same.
And, yes, since it’s a minihdmi, it’s not quite as easy as I imagined. But buying an extra cord is only $3-$4, stick an adapter in your glove compartment, and you have the advantage. I can imagine people doing that.
But the advantage isn’t quite as clear.
Apple has traditionally failed (or been worse) on the connectivity front. I have a super cheap mp3 player I bought a couple years ago. Cost less than $50. With my cheap mp3 player, I could transfer the mp3s directly to someone elses computer using a standard usb to miniusb cord. And did that a couple times. Really super easy. The person I was transferring to had apple stuff. he could not transfer his mp3s from his ipod to my computer. This isn’t directly relevant to the ipad (that I know of) but it points to the weakness of apple products in general in transferring data from the apple product to a nonapple system.
