If it really is a S10 4333-36U, this is the same one that we got from Best Buy (the wrong model). I like this model because it has an extra minipcie+3g sim where I plugged my Broadcom HD Crystal - which works btw. The only thing annoying with this one is that it has an additional fan, right below the trackpad (Some believe just to cool the 2nd minipcie slot), that is toooooo freaking noisy. It sounds like grinding as if it is touching the metal mesh grills. I read from the official Lenovo forum that it can be fixed by putting engine oil on it. Mine is still in warranty so I don't want to do that kind of thing for now. The chipset+cpu fan is silent. Its just the 2nd fan which is really annoying.
Oh, I bought mine for 199 - ($20 from rewards) .. and I got an additional $20 for the best buy error.
