5mb unifi = people who download from rapidshare/megaupload free subscriber mode. No point getting better speed if your download sources are those sorts of free file sharing sites.

10mb unifi = for people that want to download fast and share with 4 or more users. The upload is nice for a mini web server, but the bandwidth for torrent and mini server may conflict :/ meaning not enough to do both. On 10mb i spend more time thinking what to download because i download too fast    Power users wouldn't be too saddened only having 10mb instead of 20mb, especially when considering the price.

20mb unifi = expensive and honestly i don't think people need this speed at this price, not unless your planning to webhost from your unifi like i am.
But at the end of the day, you must not forget about the cap they may later enforce. If you believe the malaysian consumer will make enough complaints/waves for them to revise or remove the cap entirely, and your ok with paying for the sickening high premium price for ftth broadband, sign up. if not don't cauz it's a risk and it's pricey

I was on 1mb for a long time even when 4mb was available. The truth of matter is, tmnut has been a monopoly since independence day and till now and onwards. So i wouldn't hold my breath any longer sticking to 1mb. Just vote for new government when you get the chance. That is the only way there will be any change
