Have to say, I wasn't expecting a huge amount from this when I bought it. I expected to have many set-up problems and what not.
Set-up was painless (on Windows 7 64-bit anyway) and the software is relatively good, all be it a bit limited. For example, it is a bit buggy, sometimes sluggish and I would prefer more security/permissions options. Luckily this can be fixed later and is no real reflection of the product itself. It's also often not clear how to do some of the simple things. This is the real reason for marking it down by 1.
I haven't got to test out some things like: Printers, External Hard Drives, but I suspect these will work quite well, given the ease of everything else. It did just work out of the box with the PS3 iTunes and the likes which was nice.
Overall very happy with the product, just wish I had a better network set-up to really take advantage of it.
