It isn't bad i would think. However, ASUS have some terrible quality control issues (or had) and the infinity suffers from slow I/O issues. This causes lag and other things which could potentially get annoying and also random hangs, The stock browser might also be dire in performance. I own the transformer TF300 which has some of these issues. Regardless, i've grown to love the form factor of the keyboard and tablet and it works well. You could head over to XDA and see opinions there. I haven't used an infinity but i know that it does suffer I/O issues
