I presume that you do this with a external USB adapter? I thought to do
the same, but given that the prices for USB stick are dropping
dramatically I am not sure whether it is worth the effort.

Is this somehow connected to certain BIOS upgrade for getting
performance bursts? Like the one described in

Hm some weeks ago I wanted to buy a X1, since it looked like a very
attractive mixture between lightweight+13 inch screen+ssd, but to my
*horror* I found out that Lenovo had the brain-damaged idea to change
the keyboard. :'(

I don't mean that they changed the typing mechanism or the size of the
keys, no I mean the distribution is changed dramatically, important keys
are missing. 

Since I am a touch typist using the same keyboard  for the last 15 years,
this is as close to disaster as it gets.

I don't think there is any hope that Lenovo will see reason and will
offer, at least, a Thinkpad with the classical keyboard. So I might be
forced to buy in the future second hand models and if high tuned even
better, so I might come back to you..... :-D
