Something to ponder but here is a nice setup that I have been using and it works great for my business. I currently have 1 main POS station. I run a Quick Service home town Dairy Bar restaurant. I opted to go with the Surface Pro 3 as my main POS and I use the Surface Pro Dock and have it sitting on top of a cash drawer. The dock has Ethernet so It is in Wired mode when used 99% of time… if its picked up off Dock it switches to wireless.
Here is link to the Surface Pro 3:
Here is a link to the Dock I use:
Price may seem expensive if your weighing it as a consumer purchase but as a business purchase for mission critical use its actually quite competitive with other solutions.
I have my dock locked down to the Cash Drawer and the Drawer is bolted to my front desk. I take the tablet home every night and I do my reports and cashing out at home which is very convenient… I absolutely love the flexibility of this setup.
I will be adding more Surface Pro 3 with the core i3 models for additional terminals. My main terminal is also the server currently and it runs great… I will be switching it to use an actual Rack mounted server in the back office in next few months however. I am currently testing it now.
The surface 3 I use currently has a very very fast intel core i5 cpu. It can keep up with anything i throw at it. 12 inch screen is beautiful with SambaPOS. I personally think its nearly the perfect size for a tablet. My employees can pick the Tablet up off the dock and take it to a table or to the drive through window if ever needed to make order taking easier. I love this flexability.
The digitizer pen is very nice as well.
The dock is built very well. It adds 5 more USB ports and leaves the ones on the tablet itself available for use as well. It also adds a Mini display port and leaves the one on tablet available so you end up with 2 options for display out if needed.
Bottom line: This thing works awesome in a POS environment. The dock is rather pricy but worth it for me. The setup looks good, is very flexible, and has saved me money.
