it's nothing to get upset about, yes EVERYBODYS Surface is left with those amounts, also other devices is left with the same amount. and its no big deal to place the recovery on a USB and keep it safe, it will be just as easy as if it was on the HD of the Surface... this happens to ALL devices with 32GB HD's like I said my friends ASUS RT tablet is left with the same amount, also another friends tablet 32GB ANDROID is left with the same amount.. this isn't new or just YOUR device. and if you can't live with this or bothers you this much, then I suggest you get a Surface with 64GB which can be had cheaply nowadays! its just the facts of life in regards to tablets with small HD.
I'm not upset but I am ANNOYED. Microsoft clearly states on their website that a 32GB surface 2 should have 18GB of space left and this is the reason I went for a 32GB when purchasing my Surface. To have a third of that space missing isn't right. You buy a 20litre fridge but realise it's only 14 litres? Mis sold?
I am getting a replacement soon as this one has a screen defect and will be reporting on the storage quota on the replacement as soon as I get it and install updates etc.
