除了發表新旗艦手機 Lumia 950 之外，微軟在台灣時間 10/6 晚間的發表會也一如預測推出了 Surface Pro 4，值得注意的是，微軟在發表會中還特別提到效能將比 MacBook Air 快 50%，向 Apple 叫陣的意味格外濃厚。
在此次發表會之前，眾媒體就預測到了微軟將發表新一代 Surface，不過詳細的規格透露不多，但整體而言新的 Surface Pro 4 在規格上可說有大幅度的躍進，雖然系列已發展到第四代且競爭者愈來愈多，但以此次發表會公佈的規格來說，Surface Pro 4 在同級產品中仍相當有優勢。
首先螢幕尺寸來到 12.3 吋，採用 4K 規格，解析度為 267ppi。雖然螢幕較前一代的 10.6 吋更大，但整體寬度並沒有增加，原因在於更窄的邊框設計。觸控螢幕搭配 Microsoft Pen 可達到 1,024 級壓力辨識，具備橡皮擦功能且全面支援 Illustrator、Photoshop 等重要的修圖與設計軟體。Microsoft Pen 續航力長達一年，連點兩下（Double Click）即可擷取螢幕畫面，不使用時還可以磁吸方式固定在 Surface 上。
效能也是此次發表會的重點，Surface Pro 4 將配備第六代 Intel Core i 處理器，並採用新的 Hybrid Cooling System 散熱系統，發熱與耗電量進一步降低，最高規格將採用 16GB RAM 記憶體與 1TB SSD 固態硬碟，主鏡頭則為 800 萬畫素。發表會上更指出， Surface Pro 4 將比上一代效能快上 30%，同時也比 MacBook Air 快上 50%。
不僅如此，Surface Pro 4 尺寸更加輕薄，厚度僅 8.6mm，且為了搭配 Windows 10 內建的「Windows Hello」生物辨識，它也搭載了指紋感測器。微軟也為 Surface 推出新款的專用底座，配備多達四個 USB 3.0 連接埠、乙太網路連接埠與 4K 輸出，擴充性更強。
鍵盤套也同步更新，雖然體積更薄、重量更輕，但新的 Type Cover 觸控板體積增加了 40%，支援五點觸控，鍵距也同時加大，採用剪刀腳設計並搭載背光，鍵程增為 1.3mm，微軟宣稱這款鍵盤將讓使用者更容易打字。由於新的 Type Cover 整體寬度不變，因此仍可適用於舊款 Surface Pro 3，換言之，三代的 Type Cover 也可適用在四代上。
至於大家最關心的售價問題呢？Surface Pro 4 將於 10 月 26 日上市，售價 899 美元起，折合台幣約 29,800 元。

Originally I hoped that this sleek and stylish device can lower my burden physically.
But microsoft has really done a miserable job in supporting TV connections.
I have two sets of Sony TV and surface dock, one in my office and one at home.
Since I upgraded from Win 7 to win 8.1 and later wiin10, it has become a nightmare every time when I slide the surface pro to the docks.
Win most time just could not find the TV with hdmi or VGA adaptor to minidisplay port in the docks.
I usually have to switch on and off the surface pro like 30 mins or one hour so that finally Win finds the TV connections.
A total waste time.
I asked Microsoft for help twice.
The first time, they asked me to download a newer version of Win 8.1
It worked for a couple of days and eventually the problem emerged again to a even worse nightmare.
Then I hoped Win 10 could help.
But it does not.
Then I contacted MS for help.
They sent me mail to guide me to reset the memory of TV connections manually.
Then it worked one day.
But then the problem emerged and remained the same.
I have also surveyed the internet and found this has been a lingering problem that MS did not solve or did not care at all.
I am really disappointed.
I think we should not buy this product until its docking station has an hdmi or vga output or somewhat.
Please don't buy it if you seriously depends on the surface pro in your profession.
損壞率跟品質都很爛
