We have had 16 Dell Inspiron 640m in service for 2 years daily use without any
substantial degradation of battery life. Maybe from 4.5 =>4.
I mention this as there were a few posts that either look askance on
'consumer' models and/or dell batteries in particular.
This model is/was the same as the Vostro 1000. I would purchase either of
both of these models again without hesitation.
The battery of my Inspiron B120 went from 1.5hrs to 15mins to 0mins within 1
year. It is the unit I am typing on now, and the battery was run daily from full
charge to full drain.
We had ZERO luck with batteries in our outgoing four year old HP nx5000
models. Those batteries that were not changed under warranty were replaced at least once since then and some units currently have about 30 mins runtime
an the most 2 hours (all were 4+ in the beginning).
Everyone makes lemons (even Apple) and batteries are a consumable part, to
some extent it is luck of the draw, and how the batteries are cycled. I also
think that mfgr efforts to extend battery runtime lead to shortened battery
service life a few years back.
I am not sure how a formal grouping of purchases would work (outside of the
Adobe software thing, PRC, or the VITA learn First Class, etc program?).
But what I would be happy to do is when we seek quotes in early June for the
laptop I can get, I would be happy to try and work with any other school
interested in something similar. We will be looking for 15 units.
I will ask a couple of vendors and report back if they say anything interesting.
e.g. 15 at $700 30 at $675.
It is my understanding that the margin on hardware is not at all the high, but given the lousy economy, maybe it will be a buyers market.
ps Nice to see continued positive info about Win7.
