For a backup Internet service/light surfing needs, YES 4G is perfect, and if the MUR of RM 30 doesn't bug you, go for it, mate!

I tried it on a mate's netbook once... in a house in PJ which also had a 4M Streamyx connection.. TMNUT lost in terms of DL, UL speed lol....

Of course, its perfect if surfing and mail checking is all you do... Videos/Bulk downloads/sustained file transfers are a one way ticket to the poorhouse with yes lol...
