Asus Transformer Prime should last about 15 hours with the keyboard dock. It's based on ARM. I have no idea if Vim can work on Android, though. Maybe this will work: https://market.android.com/details?id=com.aor.droidedit&feature=more_from_developer#?t=W251bGwsMSwxLDEwMiwiY29tLmFvci5kcm9pZGVkaXQiXQ. https://market.android.com/details?id=com.aor.droidedit&.... https://market.android.com/details?id=com.touchqode.editor&feature=search_result https://market.android.com/details?id=com.touchqode.editor&#...
