I'm creating this reference to compare IBM and Dell's various models, for suggesting certain models of ThinkPad to people who want a Dell.
IBM models displayed are those available on
Lenovo's site, going to a series, and clicking on "All Models". Yes, the R51e is missing right now.
Dell models displayed are what's currently on Dell's Home and SMB sites, and has a ThinkPad analog. (The D410 is NOT the X32's analog. It's a Sonoma, whereas the X32 is an i855.) Some of it's IIRC.
In the center is IBM's lineup, sorted by series in alphabetical order, then numerical order, then grade (e then no letter then p), then size.
On the left is Dell's Inspiron lineup. On the right is Dell's Latitude lineup.

Changelog:
Version 0.3.0, 2005-11-30
Since the B120 and B130 have replaced the 1200 and 2200 respectively, this has all been fixed. Changes in the widescreen area, as the B130 is a widescreen.
Added the XPS M140.
This is probably going to need bugfixes, as I don't know about other models yet.
Version 0.2.5, 2005-10-10
Added role descriptions
Version 0.2.1, 2005-10-10
Dell really did hide the 110L, now, didn't they? Didn't show up in the Latitude lineup...

Anyway, it's added as an analog to the R50e.
Version 0.2, 2005-10-10
Added XPS and Precision columns, extended D610 to cover T42, added M20 to cover T42p/T43p, added D510 to cover R51/R52, added D410 to cover X32, added X1 to cover X40/X41, added M70 to cover high-end Z60m (questionable)
Version 0.1, 2005-10-09

Any suggestions to improve this table?
