The Acer Iconia A700 may offer mediocre performance when compared to the Asus Transformer Pad Infinity (TF700), but it's also normally $50 cheaper than the TF700 - to those on a budget, that may be a worthy sacrifice. Perhaps doubly so now that it's on sale for just $430 on Amazon (compared to $500 for the TF700) - certainly an impressively low price for a 10" 1920x1200 tablet powered by a Tegra 3 CPU.
