Well I think that you should not buy the $99 PC from Walmart because it would not be good quality. The PC would crash all the time and you would not get your money's worth and it would break withing a few months.
So you are going to buy crap for Christmas. Why would you give them a present that is only going to last a few months. There are other things that are more worth their money that you should buy instead of the cheap crappy PC
But every kid wants and Apple not the other brands that are not even really popular. My mom always said that if the price is not reasonable which $99 is not a good price for a piece of junk, the don't buy it. You might as well buy them something that they would actually enjoy like an iPad than this computer. So I think that you should save your money!!!
