Your calculation there is fantastic bro

New insights!
If you are looking to cover the "cost" of either laptop by selling them, by all means you can do it. But if you are looking to profit beyond the full cost of "$840 HP" or "$1320 Alienware", I feel both are risky, but alienware may have slight edge in terms of reselling.
Well if its for your own use, then you have mentioned, HP is mobile and sleek, Alienware is a beast and also a beastly size. For me its the former as I don't game, though I don't like HP
Personally I think we won't see a flood of HP after this show because wise dudes know effectively they are paying for the notebook and history points to the fact that nobody can really profit from it, it will just lead to pricewar and every seller suffer.
SingTel promotions not like M1 at all. No matter how you calculate, you will end up paying for the notebook, which is listed very clearly in this show as top up $35/$55 for the premium. M1 does it so well that it used to be at $79, you get a 100m + mobile line worth $36/mth + home line + notebook, that was seriously uh, how m1 earn but rejoice to end users
So if you want to use, by all means sign for it, but if you want to sell it, don't risk your future cash.
