I test drove the Mega for a few days and while its nice and big I could really feel the lower specs. It was constantly running low on RAM and gaming was noticably choppy. Unless you're gonna be a very light user (who's not gonma do much gaming at all) you may want to consider a different handset. Note 2 maybe? I'm not putting the phone down I'm just saying that the lower specs really do have an impact on the experience.
Note 8.0
