Memory And Storage
Now that music, games, apps and pretty much everything is stored locally on a smartphone, memory and storage must be bulky, lest you run out of room and have to sacrifice.
The Apple iPhone 4 comes in two storage flavors: 16 GB and 32 GB.
Meanwhile, the Motorola Droid X comes with 8 GB of onboard memory and a pre-installed 16-GB memory card. But it can be beefed up to 40 GB with the addition of a 32-GB memory card.
Winner: Motorola Droid X. Expandable memory is a key differentiator here and the ability to swap in a 32-GB memory card gives the Droid X an 8 GB storage edge over the iPhone 4's max of 32 GB.
