I like Surface pro 8, it is light weight, well design, it is also easy to upgrade the SSD storage space.
The downside is the RAM not upgradable.
I paid for the 8GB Ram and 128Gb SSD, and it is only cost £800, plus the keyboard £150.
I feel it is well worth the money, there are 16GB Ram choice as well.
I5 is good value comparing with i7.
The following video is for how to upgrade the SSD, you need M.2 2230 SSD, Dell is selling those SSD.
