It appears that Microsoft is getting ready to announce an upgrade to the Surface Pro 4. Based on the reports, it will be an incremental upgrade, with a bump in the processor and system specs.
No USB-C, but I think that’s a good thing. USB-C is still too new, and Apple didn’t do itself any favors by releasing a laptop with only USB-C ports.
I have a Surface Pro 4 and I really like it. I finished writing my FROSTBORN fantasy series on a Surface Pro 4.
