Asus Transformer Prime - Buy now or not???

That may be, but from what I have read, Asus is reparing the 201s under warranty, by replacing the backs with a new one.
Unless you have had yours fixed under warranty and can say for certain that the fix is not a new back, I will tent to hold to what I heard earlier.
If you have had yours fixed then I defer to your warranty experience.
I owned two primes from BBuy and I returned both of them due to horrible backlight bleed. Weak wifi and BT/WIFI fallout is the primary culprit. You're in for a world of hurt, IF, you get the wrong prime. As far as I've seen, its a gamble.
