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.
Fun fact: a 1080p display packs 2,073,600 pixels. The Asus Transformer Pad Infinity (or TF700)? 2,304,000 - or 230,400 more. Most 1080p HDTVs are somewhere around 40-60 inches. The TF700 checks in at just 10. Compared to a 40" HDTV, that's 111% of the pixels in a package that's 6.25% of the size.
The screen may be the real headline feature with the Infinity, but it's not the only one worthy of note.
