The D2 is a great phone, as is the Bionic. However the Bionic did not meet the standards I had thought it would. The 4G is amazing. It's faster than WiFi on my D2. The GPS is quicker, and the screen is better in the sun. But... I experience UI lag even with the dual-core processor! It's not a great phone if you like high graphic games. The fps are choppy. Lastly, the keyboard for texting is surprisingly awkward. I make many typos. I'm within my 14 day return policy and will be returning my Bionic to reactivate my D2 until the Rezound is released in just over a week.
I thought I'd share my experience for anyone debating an upgrade to a Bionic.
