Spend the remaining of your budget to increase RAM (4G stick is ~ RM100), extend warranty (Dell, extend to 3 years for ~ RM300), swap SSD (128G ~ RM300, 256G ~ RM600) in for HDD.
thanks for your recommendations, but i found difficulties after you recommendations, that is i can't found any review about the laptops and even tech specs of lenovo models~
even though i found it in the computer shop, but no brochure for reference too. what can i do if i want to do comparisons for these laptops?
would you recommend Lenovo Z400 touch, Z500 touch, G400s and Z480 for my usage? since these models are still within my budget. thanks.
