come on..... laptop will just keep update and update

There will be a spacing if you opt for the 9- cell battery hehe 
If not, just raise it with some books/cooler pads?

basic model of dell super many problems, beyond as mention, not advised. esp if u go international to change.. not a single help unless pay handeling service n fixing charge, not to mention shipping
xps got probs but not as many complaints. but still gt probs like heat caused probs(ventilation bad design- thy sud get the alien designers for them like what hp did with beats for sound) monitor- blackouts, hhd crash.these is main probs.. and to top it off u are still paying premium price for and xps 15 or xps 16 studio

warrenty i dun think itz great but if within malaysia u get ok cover. my other frend 4 months bought, bring australia, hdd fail.. reformat not cover.. 8 months.. screen fail.. not cover... she got soo angry and when i told her dell main probs she got mad at me... nvr warn pple early..now im warning pple if they wan go international paying the conversion price while in white countries where labour are expensive.. gud luck fixing it

i got a chance to play with it n its laggy. did the 5 fingers touch thinggy , chosen an application n it takes like more then 10 sec to open n more time to fully load! the sales rep try to cover that by showing the lid can be fully 180 deg flat. even after showing that , it still loads things.

aahhh , those choices make me giddy lolol
actually 5750g > 4830 in specs is with i7 only rite ?
but as most ppl say , 4830th design too cantik liao , slimmmm LOL

Depends what ur laptop is la.. I5 dual core only supports 1066.. Only i7-quad can support 1333mhz

DDR3 is a must, they can't fit other type RAM..
1333MHz would need 3rd party apps to check like CPU-Z, AIDA64, etc..

Definitely 
Currently the most awaited ones are the Alienware M11x R3, M14x and M18x
