The OP forgot one advantage
This is the only advantage which I honestly believe is a real one: Using Windows 10 also gets you access to a free copy of Minecraft, the Windows 10 version. Granted: it's not as extensive as the normal one which you buy from Mojang, but it may give you a free and nearly complete insight look into the world of Minecraft.
Warning: heavy bias follows.
And Minecraft is an amazing game. It's not for everyone, obviously, but I do wish to implore some people to look beyond the initial (and maybe uninviting) blockery landscape and to just try and discover the world a bit. Minecraft may look very simplistic on the outside, but on the inside it could easily be much more complex than you may give it credit for. Its much more than merely a game where you place colored blocks on top of each other to mimic real world imagery (even though it can easily be used for that!).
For me personally Minecraft is the combination of things. An adventure game: when mining resources (such as coal, iron, diamond and maybe redstone and lapis) you'll no doubt come across dark caves. Even though they're automatically generated (and eventually you may discover some vague patterns) they never stop to amuse me. Because what could be lurking within? You'll no doubt come across hostile monsters (mobs), and to prevent them from spawning in you need to light the place up. Challenge #1: make sure to keep enough torches. But it's not merely caves, you can also come across abandoned mineshafts (its just what it says) which includes occasional minecarts which have chests in them with extra spoils to collect. Or strongholds, which not only contain a mysterious portal which - when repaired - teleports you to another dimension but also other interesting things like libraries (with the cobwebs and bookcases, all you'd expect in an ancient unused library).
What to do with all those spoils? It's up to you really. You can make tools from wood, but it pays off to get better materials such as stone, iron, gold and best of all: diamond. The latter also allow you to make armor, which helps to protect yourself from any hostile mobs. But lets start simple: stone. You can process your stone. When mining stone you'll end up with cobble stone, but cook it and you can get the regular stone block back. Of course you'll need more: you need to build yourself a furnace first (using cobblestone) and it needs to be fueled too (using wood, charcoal, coal or more exotic things like a lava bucket or a blaze rod). Speaking of wood: you'll need lots of that too. For starters to make a crafting table which allows you to make more complex items (such as the previously mentioned furnace). There's plenty of wood to be found in Minecraft: Oak, Birch, Acacia trees which all have their unique looks right down to the huge ones like Jungle, Dark Oak and the Spruce trees. Challenge #2: when chopping wood you'll come across saplings. Collect them and use those to make a tree farm: your own endless wood source.
So about that stone: cobblestone can be used to craft stair blocks and wall blocks. Cook it (see above) and you get the (regular) stone block back. Stone can be used to craft stone bricks; this is basically stone with a brick "pattern" on it (looks awesome on walls and floors). And these can also be crafted into stairs to add to the diversity.
Not enough for you? Use 3 stone bricks and make stone brick slabs (a slab is basically half a regular block). Now combine 2 slabs together and you get chiseled stone bricks: a stone block with a square pattern on it.
Sounds complicated already? I've only scratched the surface here. You can also make those stairs and slabs from wood, sandstone (can be crafted from sand), nether bricks, etc. Speaking of sand: collect that, cook it and you got glass.
And this was only about crafting building blocks. When we're talking redstone you're looking at a setup where you can even build your own computers. Think I'm joking? here is a youtube video which demonstrates a 1kb memory module in Minecraft. I'll leave you to look up minecraft computers on either Google or Youtube :)
SO yeah, it's not all bad :P Though I'll be the first to admit that as awesome as I think Minecraft is it should not be a motivation to upgrade to Win10.
