X200/X201 had a huge bezel. And, from my experience with X200, there is no difference in external dimensions between TN (stock one), IPS (HV121WX4) and MVA (LTN121AP02) panels; all three have their bezels only 3-4mm thick. What takes the space are ultraconnect antennas and their wiring.
also with inner space needed to accomodate Sandy Bridge platform.
Four generations (X40, X41, X60, X61) had thin bezels. Three following generations (X200, X201, X220) have thick bezels. Do you really think that the reason is some limitation of sandy bridge platform?
form factor is bigger than X220 (Area 632,48 sq cmts vs 621,65).
It seems you're mistaking something. It could be clearly seen from the photo and from official specs that X40 is rougly as deep as X220, while being much shorter.
X40 area is 26.8*21.1cm=565.48sq.cm, and X220 area is 30.5*20.6cm=629.82cm, or about 10% larger.
In the same time, X40 display area is 453sq.cm (80% of laptop's area), and X220 display area is 5% smaller, being 430sq.cm (68% of laptop's area)
As to display yes, apparently more real state but what do we have here? XGA (1024 x 768) res.
AFAIK there was an option of 1400*1050 or maybe even 1600*1200. Both are better than X220's 1366*768 and even than X200s/X201s' 1440*900.
Other innards of X40: 512 MB RAM, ULV Pentium M (1,06ghz).
That's not a lenovo achievement but intel's one. Of course when i posted here a comparison photo of X40 (2005) vs. X220 (2011), i in no way thought of comparing their internals.
