yo bro suadrif here is my feedback on the speaker:-

Basically I just install the Win7 ultimate (pirate version) without any proper driver from Realtek, it works decently. It work out of the box in Windows 7.

To compare, the sound is not as loud as my company lappie which is Lenovo T420s. I don't really listen to music via laptop speaker 

One more thing I want to mention here, for those who have some doubt with the UEFI, it can be switched to Legacy mode and the Secure Boot can be turned off too. So for those Linux enthusiast, there is no worries installing your favorite distro on it.

I did have a look at the 5460 over the weekend. However, I am not convinced that it is the best option if you are looking at it spec wise.

hi guys, im very tempting to buy this vostro 5460, got this quotation from dell, good enuf or should i tawar-menawar further?   

just bought 5460 yesterday, rm1750 i5/4gb. but im having problem installing win7 via external dvd..anyone can help??pleaseeee????

few forumers reported that the sound is just ok, not so bad and not so good
but if u insist for nice speaker, toshiba is a better option
