File this under a good problem to have but it looks like Microsoft has temporarily stopped pre-orders for all Surface Book models. Over the last few days, the Core i7 variants began to shift from pre-order to 'Email me when available' and now it is all variants of the new two-in-one device.

It is telling that the most expensive version – the top of the line Core i7 with 512 GB of storage and 16 GB of RAM – was the very first to go unavailable starting a few days ago.

Of course, you can still preorder the device from other outlets like Amazon and Best Buy – for now, but that $2,699 version is unavailable everywhere. Granted, Microsoft likely allocated only a certain amount of production units, which may have been a small amount. The company is likely ramping up production requests to meet demand, but it remains to be seen how long that will take.

For now, we can't say the Surface Book is a hit, but it's starting to feel that way.

Microsoft did tell some in the media last week that interest and demand for the Surface Book were higher than expected and that looks to remain the case.

Hopefully, Microsoft can adjust production and they will re-open orders as soon as possible. We haven't checked our local Microsoft Store to see what their status is, so if you live near one, it may be worth a shot.

Windows Central will follow-up when the Microsoft Store gets more in for pre-order.
