I've used it briefly on a business trip. It leaves okayish impression, but few things were of a constant annoyance: * Fn-key in the left corner, yuck (luckily, can be swapped in BIOS) * No scroll lock key * %%PgUp%%/%%PgDn%% are split and swapped (%%PgUp%% is on the left, %%PgDn%% on the right, unnatural and confusing) * Home/End/Insert/Delete block in the top row (hard to reach from the lower navigation block) Good things: * Extended battery is awesome for the longevity and is not annoying in daily use (e.g. on the table) and helps for air intake. But it makes working //on a lap// very uncomfortable unless you put something thick between it and your legs due to those small sharp rubber stands * Has both classic “clitoris” and touch pad, supports some basic multigestures, e.g. natural scrolling is cool * Keys are OK, nothing special, a bit too noisy, no keyboard backlight nor rim lamp * No proprietary HDMI, good; has VGA and mDP ports for external video * Lid can be opened at 180°, that's nice, I sometimes find it useful The best part is battery life, it's really impressive (10-12 hours); overall this laptop is not %%FreeBSD%%-friendly. ==== Boot-up and bare console behavior ==== Boots recent 12.0-CURRENT-[[http://svnweb.freebsd.org/base?view=revision&revision=330450|r330450]] more or less fine, but is unable to switch the screen to native resolution (with or without ''%%i915kms.ko%%'' modules loaded). Suspends, but does not resume properly (well, //sometimes// it kind of does, but with a blank screen). Often even cannot shutdown or reboot itself (hangs hard and requires full powercycling with the power button). X.org starts but I haven't tested it beyond that (e.g. hardware acceleration or behavior of %%OpenGL%% programs). ==== Bluetooth ==== Apparently it fails to initialize properly: ubt0: on usbus0 WARNING: attempt to domain_add(bluetooth) after domainfinalize() WARNING: attempt to domain_add(netgraph) after domainfinalize() ubt0: ubt_ctrl_write_callback:782: control transfer failed: USB_ERR_TIMEOUT ng_hci_process_command_timeout: ubt0hci - unable to complete HCI command OGF=0x3, OCF=0x3.
