Workhorse (W), Global (G) and Entry(E) -- Terminology

[mobileage]

Can someone explain me the significance of these terms? I am newbie to this terminology.
For example:
The 2373-HTU model has "G" assocaited with it. What does it actually mean? Is it something related to entry-level, medium and higher level.

I have couple questions related to other topics:

1. Difference betqween HS vs U for HDD? Is it related to speed (rpm)?
2. What is EasyServ (warranty)?

Thanks in advance.

The "G" refers to Global meaning this exact model is available worldwide. It's a comfort thing for large companies who want to standardize on a single model for all their offices.

HS = High Speed, 5400RPM

U = Ultra High Speed, 7200RPM

EasyServ is the IBM warranty service center.

Thanks James.

I have also noticed that T42's 2373 models with Pentium M 735 processor and 512MB cache have "W" associated. So does that mean they are more suited for applications which require more cache memory?

The "W" or Workhorse characterization is, again, a way for IBM to make some models more attractive to larger companies.

What the "W" means is that if you have two Thinkpads exactly alike in all ways except one is a Workhorse model, that model will be manufactured for at least 12 months after the non-Workhorse model has ceased production.
