The EVO and all other Android devices hav stingy minimal built-in storage (originally 256mb, now 512mb since the OS didn't fit anymore). They all have SD card slots, but they need an SD card inserted at all times to not break apps. They've all moved the slots to underneath the battery and given up the pretense of it really being removable storage.
