Hello all, Long time lurker but due to recent events this is my first post. I've been a SP3 user since last year but the SB has really caught my attention. From the website it seems that the SB and SP4 use the same CPU. Would that then mean that without the dGPU that you could expect identical performance from the SB as the SP4? Wouldn't they be the same computer technically? I'm a bit torn between getting the SB or SP4. Another thing I was wondering was if the SB is going to have the same (or better) hybrid cooling system the SP4 does. Fan noise and heat are a real issue for me and it becomes a problem sometimes with the SP3. I'm very excited for these products and Microsoft has really been on the ball since the release of the SP3! I'm even pondering getting the band 2 and I've never bought any of these fitness trackers before.
