Thunderbird is not something one can recommend to a non-techie friend as a replacement for GMail. At least the last time I checked on Android, it required additional tuning for pushes, it worked poorly when there was too many messages in inbox (which is what almost everyone coming from Gmail has), didn't provide text formatting.
