Sadly, the Sputnik version of the XPS 13, the one I was more interested in, still has issues/hasn't come out yet. This 3rd-party article/thread seems to be a good place for tracking those developments: <a href="https://major.io/2015/02/03/linux-support-dell-xps-13-9343-2015-model/" rel="nofollow">https://major.io/2015/02/03/linux-support-dell-xps-13-9343-2...</a><p>Issues w/ the XPS 13 include keyboard repeat issues (fixed w/ BIOS A01 update), trackpad issues (kernel patches, switching from I2C to PS2 mode), sound (switching from I2S to HDA, requires ACPI jigger-pokery including another kernel patch since the BIOS breaks sound init when ACPI is sent properly <a href="https://lkml.org/lkml/2015/3/12/149" rel="nofollow">https://lkml.org/lkml/2015/3/12/149</a>). Also the XPS 13 uses a somewhat flakey Broadcom wireless card as well. And people have reported some S3 sleep issues.<p>My main goal was to replace my MBA11 w/ something about the same size w/ better battery-life (my Yosemite battery-life is pathetic, about 4hrs even just web browsing). The FHD XPS13 claims 15 hours, but I couldn't wait anymore and ended up going w/ the new Lenovo X250 - slightly less sexy but more or less equivalent and only a tiny bit larger, largely works OOTB w/ Linux, and has 20 hours claimed battery life w/ the 6-cell battery option.
