The fact that you've heard of an iPad makes it significantly more likely you would choose it over the competitors even in a Best Buy. There have been mp3 players that were better than the iPod throughout pretty much it's entire existence, and they sat right next to the iPods at Best Buy and Wal-mart. They didn't put a dent in iPod sales at all. The only one that was wildly successful was the Sandisk Sansa, and the price/feature differential was such that saying it competes with the iPod is like saying Kia competes with Ferrari.
It'll be the same with these two tablets. People may buy the $200 thing because it's cheaper. Some (maybe even myself) might buy it because it's hackable. But nobody who wants an iPad will buy this instead, therefore they don't really "compete" by any meaningful usage of the word.
