I am planning to soon buy a 27 in. iMac. For a part time business at home, I have 4 printers/scanners to connect as well as at least one external drive. I am considering a powered USB 3.0 4-port hub (maybe the Belken they have at the Apple store). An alternative I have read about is a Thunderbolt hub, such as one from OWC. This would give me 5 USB ports and also allow a direct 2nd monitor connection by HDMI. Any thoughts? Worth the extra $$ for the Thunderbolt hub? Will all printers and drives work as well on either type? Thanks in advance.
