I went into the Verizon store planning to upgrade my D1 to a D3. The main performance issue I have with my D1 is when I'm running multiple apps at once such as playing music (using Subsonic) while browsing or using maps. In the store I tried cycling through Maps gallery, browsing, flash etc and the D3 performed great. Then I wondered over to the Bionic and tried the same test and everything felt just a bit faster. AFIK they have nearly identical hardware except for the Bionic having 2x the ram but I'm pretty sure I never reached the point where the D3 was closing apps to make room for others so that shouldn't matter. Does anyone with experience with both phones have thoughts on the matter?
