However, I will only add it if I see it's needed. Wifey's laptop use is very basic and not demanding. she hardly does anything other than upload pics, basic browsing and word processing etc.
I am the one who does all the RAM demanding stuff. I of course max out whatever PCs I use.
Now I am jealous...perhaps i should get my dream T420 too?
right now my ancient ThinkPad R60 is chugging along on Ubuntu...but...upgrade bug has bitten me, too...
IDK perhaps i should wait and see if there are Xmas deals..
For $47 shipped, dump in 8GB regardless. You'll be future proofing it to an extent and you're wife will see a performance improvement. Heck you popped for the i5 which has the fancy "turbo boost" functions. May as well take full advantage of Sandy Bridge and bump the RAM to at least 8GB. 4GB is getting to be the new minimum with Win 7. Yes it will run just fine 4GB or even 3 but its much snappier with 8.
Also don't forget, the 4GB they are sending you is likely in the form of a single 4GB stick so you don't have the RAM running dual channel mode. In single channel mode your memory bus width is only 64bits vs 128bits in dual channel. The maximum theoretical bandwidth with DDR3-1333 goes form 10.6GB/s in single channel mode to 21.3GB/s in dual channel mode.
If they shipped the computer with 2x2GB operating in dual channel mode, I might say pass on the upgrade to an 8GB dual channel kit if she doesn't do any memory intensive tasks. However, IIRC the spec sheet for the Edge you bought your wife (was looking at one for my wife too) states that its a single 4GB stick.
