I bought two of these as I work in cyber security and I didn't feel like taking the others off the VESA mounts and stands (although one is a 3D 120Hz monitor with dual DVI AND two HDMI A ports). All in all, Acer builds decent stuff - I work for Dell Services (Dell Servers and Storage now with the VMWARE EMC Airtwarch merger is odd). Dell servers are still made in Austin and Alienware is also still in Flodia. Their main rivals will probably be Apple Lenovo as far as end user computing. This model has 2 USB 3.9 ports, 1 USB 2.0 MHL low power mobile charging port. SDXC card card reader (even a CAT5/6 port too yay) although the card reader still sticks out like the Yoga 2 Pro for some reason. A lttile heavy and don't believe the keyboard backlight, there is none I would know and I'm look for a FLEX 4-1570 that may have it and fit. Touchscreen and as close to a real Pentium as one has had in a decade. Good BIOS Support, no smart card or biometric but that can be mitigated. Virtualization is possible and I think the COU issue 4430U with hyper threads. One UDIMM silt and PITA to get to but it's DDR4 16GB yu can upgrade to, I put a Consair FORCELE SATA 3 256GB which makes a Serious difference. The only think I find annoying is weight compared to the YOGA 2 ands other competitors similar models. The back does not fold entirely flat as a tabel an owners should be able to but close and the resolution is closer to 720p even though I speculate that though who want 1080p will use the HDMI port. For $399 it's a good value if you do may upgrades - AND LENOVOV PICK A POWER CONNECTOR - I HAVE A YELLOW SQUARE A YEAR AGO ON THE LENOVO YOGA 2 PRO but something entirely different on this model. AND ADDD THE RUBISIZED POWER COATED FEEL - GO FOR THE BEST!!! - Brian Network Security Sr Advisor Dell
