The folks at the Verge has created a nifty comparison table between the ASUS EEE Pad Transformer Prime (TF201) VS the original ASUS EEE Pad Transformer (TF101). Check out the source below to see the match up. Also take note that ASUS Will still be selling the first generation Transformer and it is to be considered as a mainstream tablet for the masses while the Transformer Prime will be marketed as the premium tablet for those who want to experience the raw power of the new NVIDIA Tegra 3 Processor.
This makes sense as the recently launched Xoom 2 specifications aren't exactly mindblowing and the original Transformer could still go toe-to-toe with it without any major issues, so it is only logical for ASUS to continue selling the first-gen Transformer to rack up tablet sales. Anyway, check out the source below for the comparison between Prime TF201 and the original Transformer TF101.
