Laptops Planning upgrades for laptops this Gitex

1. Asus N80VN-X1: C2D t5800, 4gb ddr2 800, 250gb sata hdd.
Planning to upgrade the ram to 8gb, adding intel turbo memory 4gb and replacing the hdd with a 128gb SSD if at all its affordable, What difference will SSD make ?...This laptop doesnt have bluetooth, do i get bluetooth internal cards or something ? and where do i put it.

2.Hp DV 3 series(new model): planning ram upgrade to 8gb from 4gb ddr2 and hdd upgrade to 1TB from 500gb

3.Apple Macbook pro ( unibody): Planning hdd upgrade to 1tb from 250gb.

Suggestions welcome.

Thank you
