Currys has sold out of the 256 GB version of the tablet, but the 64 and 128 versions are still available, while Argos is out of the 64 GB model as is the official Microsoft Store UK website. The John Lewis website shows the 256 and 512 GB versions as not currently in stock.
All in all, it looks like the Surface Pro 3 is available in limited quantities, but that some stores are out of specific versions. Huffington Post UK got a statement from Microsoft which said:
""People's response to Surface Pro 3 has been positive. Our primary goal is and will remain to get Surface into the hands of all productive people who want a tablet that matches their unique productivity needs. For those eager to buy, we recommend they go to JLP, Dixons and Argos."
If you live in the UK, have you had issues buying your desired version of the Surface Pro 3? Thanks to Tony for the tip!
