I really like the new (used) X41T and have been using it almost exclusively as a OneNote notebook for medical school but it's not quite fast enough for me for everyday use. The SATA conversion looks slightly difficult and something that I would have to attempt on break, but it seems like dropping in a SATA HDD will have similar performance effects as a Lenovo SSD. Am I right?
Also an idea is performing the SATA conversion and using a SATA SSD. I'm assuming that newer SSD's are better and faster than the Lenovo one, and might come with TRIM support.
Of course, I'm half tempted to buy a used X61T instead, but my wife would be much happier if I never bought another computer again.
