Also, consider using swap *only* on microSD, and using *internal* eMMC partition for ED (eliminates plentora of I/O conflicts on eMMC). If all of those is valid, maybe You have some memory-hungry widgets or whatsnot? I'm quite minimalistic in that matter, so my "standby" memory footprint is relatively small. On the other hand, full-fledged browsers like Chromium are memory hogs, so every megabyte saving You from using swaps count here.

BTW, of course, preferences wary - for me, opera isn't any alternative to microB or Chromium via ED (any single of them).
