I’ve been jonesing for a P52, P1 or Extreme X1, but have read some Lenovo and other threads about some problems with Thunderbolt implementation, BIOS changes bricking some, and some odd latency issues. Anyone know if these issues have been worked out? I’ve got a 7 year old Thinkpad that’s been like a recording tank for me, so I tend to be partial toward Lenovo’s.
