I too have grabbed the XPS 13 with 1165 CPU and Intel Iris XE
11th Gen processor, with integrated graphics about 500% better than Intel HD620.
But most of the issue for me was that Dell's advanced replacement service on my monitors involves bringing me a new one to set up and collecting the faulty item a day later. Microsoft, on the other hand, expected me to send my SB3 back and wait two weeks for a replacement. Not acceptable on £2000 worth of purchase.
At this point, the SB3 and Surface Laptops are redundant, literally no competiiton for Razer or Dell with 11th Gen innards or for the new Apple M1 chips.
By the time Microsoft deliver 11th Gen processors or new AMD mobile processors the likes of Dell and Razer et al will have delivered whatever Q2 offerings are available and Surface will be another underwhelming out of date release.
Saddens me. Greatly.
