Howdy Folks, I have been happily using my Surface Pro (128 GB) for the past (almost) 3 years. It is time to upgrade to the latest version, but I am currently trying to assess which model of the SP4 would be "best". The price for the i5 model with more RAM and SSD than my current SP costs $1300, which is quite a bit. There is the base model with a much slower (in clock speed) Core M3 processor at a much better price of $900, and the slightly upgraded i5 version at $1000. Neither of these give me more storage or RAM, just a screen/pen/battery upgrade. Has anyone compared the base m3 against the original SP, or have a recommendation on which is the best upgrade from a SP at a reasonable price? Thanks!
