Bests & Worsts Reviews from Amazon

I received the SP4 one day after it was released and I have been working with it now for three weeks. I have been using a MacBook Pro 15" inch for the last 7 years and iPad since 2011. Here are my impressions: - I think the best use for the SP4 is a "mobile desktop". The SP4 shines when connected to an external monitor and wireless keyboard & mouse. I say mobile desktop because it is 1.7 lbs, so moving it between my home office and work office is extremely easy. Just plug it and you have a full powerful desktop. I give it here 5/5 stars. I would give my older Macbook Pro 4/5 because is is heavier, 4.7 lbs, to carry around - I think the second best use is tablet. While its SW is not optimized for touch and it is not light like iPad Air (1lb), I still think the combination of the large screen 12" (dedicated for single app), kickstand, and stylus is great, so I give it in that regard 4/5 and I give my iPad 3.5/5. - I think the worst use for SP4 is laptop mode. In laptop mode, the screen becomes small for multiple apps; furthermore, the highly reflective screen makes it hard to work for a long time on it. I give it here a score of 3/5 while I give my Macbook Pro 5/5. Overall I give it 3/5 because of the poor battery life that does not last beyond 4-5 hours of real use. Is it for you? It depends on how to use it. If you are a road warrior always working in hotels, airplanes and cafes, then I do not think you should get it. If you plan to spend 70-80% of the time pairing it with a large screen and wireless keyboard then definitely get it. If you really need a stylus (teachers and students) in tablet mode then get it. If there is no urgent need, then you should wait because the SW has lots of bugs and MS is still rolling out critical updates. In terms of HW, I feel the worst aspects are 1) poor battery life, 2) high reflectively screen, 3) power button next to volume button, and 4) one USB slot. Update Jan 30: After 3 months of use of SP4, I definitely can tell that I HATE it because it is so riddled with bugs that make it so unreliable! Everyday I feel like swearing to it and smashing on the wall. Battery life dropped to the point that I can't even get 3.5 hours of use! Somebody should seriously consider filing a class action law against Microsoft for selling such an immature product and making false claims about its battery and capabilities. Update July 14: Despite months since its release, the bugs in the system are there. After working a bit this morning using the power supply, I shutdown (not sleep) the surface and went to work. One hour later, I pick my surface out only to find its pretty warm. I booted it up. It crashed during booting. I rebooted it again. This time it worked but 50% of the battery was gone!
