Pros & Cons of installing MS Silverlight for Windows 7??

I have W7 Home installed in my HP's laptop with 2GB RAMs and AMD Dual core. Recently I have been reminded through MS update that I could choose to install their "Silverlight" update in my laptop. I have been reading briefly on the MS Site about the Silverlight features and vaguely know what it is. However I have no ideas whether it would slow down or/and have other ill effects on my laptop IF I chose to install it, and if I might to beef up my laptop (such as increased its memory or graphic capability) prior to installing it. Besides, I have very limited HD capability (such as NO HDMI and Blue-Ray) in my current laptop! Therefore is it really worth this possible troubles at all for me???

Thank you for your comments in advance.

P.S: The same comments may apply for installing MS's Windows 7 SP1 as I been thinking of its possible "cons" prior to its installation as well.

IMO, you only need Silverlight if you browse sites (or have web apps) that use it.

SP1 is a good install - on my laptop, the used RAM after booting dropped by around 200Mb (admittedly, it has 4GB so I wasn't particularly worried about RDM usage pre SP1)..

It's Micro$oft's equivalent to Flash. If you access a site that needs it, it will offer to install it.

i got it on my computer, but I don't think it have been used. Silverlight was going to be the replacement for Flash, or that is how Microsoft saw it, but it failed.

Why do people still put $ in the spelling of Microsoft and Sky still? seems a bit childish to me.
they are companies, they are there to make money, if they don't make money they will cease to be simple as that and then where will we be?

I would not miss Sky, but I think the world would miss Microsoft, how ever much you like or dislike them.

Why do people simply repeat other people's posts adding no new information?

Thought you'd like to know.

Silverlight is used by Eurosport Player and by netflix.

windows is still reasonable value for money, as microsoft have yet to copy what others do and charge annual subscriptions for updates so because of that its good value, eg. XP lasted for about 10 years for its price.

Technet was brilliant value till microsoft nerfed it, even the nerfed version is good value tho and especially if you also want office.
