While the idea of a dock with a smartphone and larger display hasn't caught on with other similar products in the past, analysts said DeX could be purchased by up to 15% of enterprise customers who buy the S8. "Think of DeX as a replacement for something like a Chromebook," Gold said.
Patrick Moorhead, an analyst at Moor Insights & Strategy, said he has been using the DeX already. "DeX is a great start to Samsung's modularity capability," he said. "It's not perfect, but has improved the craft."
IDC's Bassett said that Microsoft's approach with Continuum, to run Windows productivity software potentially on all devices, even Android, makes DeX more compelling, even if it will be a niche device at the start.
Buyers in the U.S. won't get the Bixby digital assistant in the S8 right away, but analysts said they don't see that missing feature as hindering many enterprise-related sales.
While analysts agreed that iPhone will remain the top choice of enterprise users, Samsung's high-end Galaxy devices will come in second and will be bolstered by the S8.
Four analysts said in interviews that Samsung's new battery safety testing processes should protect against any overheating problems with the S8.
"Samsung really pulled out all the tops for a safe device this time after everybody was shocked, surprised and devastated with the Note7, which was hailed as the best until they had that battery problem," Bassett said.
"The buyers who were not totally disheartened by the Note7 will come back to the S8, which is getting even better reviews," Bassett added. "Remember, Samsung had trouble getting people to send the Note7 back. Samsung has set its eyes on the enterprise, particularly with the S8. They will move a lot of devices for business users."
