I saw John Carter and it was a pretty average movie, and it could have probably been made for 1/4 to 1/2 of the budget without really hurting the movie. I watched it after it was a well known "flop" and I kept wondering why someone was willing to bet so heavily on it ...
It may not be entirely fair to call the PS-Vita a flop, but it is certainly a troubled platform that has had disappointing sales to date. The PS-Vita was expected to sell 16 million units in its first year and will likely sell around 5 million, and sales are roughly half what the PSP or PS3's sales were.
Microsoft's surface was probably left off the list because there are no solid sales numbers yet. If some of the sales projections are accurate, it is selling at about 1/4 of its projected sales rate and its sales are less than 10% of the more popular Apple and Android tablets; which could probably justify a spot on one of these lists.
