er...
tsk tisk ,,,,and I try(ed) so hard NOT to write a thesis here on things ,,,, lol 
....
a) PPTs = Presentations via MS Powerpoint were done to cater for the "screen layout" of the USER (major Decision Maker @Customer site) and since we knew most people at this (& lots of other) company(ies) ARE NOW on newer laptops - thus the 16:9 screen layout (which you and lots of pple hate!!). So in short, be smart, and cater for the CUSTOMER and its WIN WIN for all (er....its call BUSINESS!!)
b) Presentations were done @
Ingolstadt with LAPTOPS on to VERY LARGE screens via 16:9 projector(s) & on 100inch LG-HD displays -
which they advised us to use (trust my German friends to have the Latest&Greatest Tech Toys - nothing but the best ey!)
b) Set up on these was the easiest and nothing to do really
(not like other times one had to fiddle around to get the "right screen size to make PPT's look as good as you can - as often your laptop resolutions ddnt cater for often crapy numerious 'displays' that you run into !!)
c) FOR PEOPLE who often do these kinds of PRESENTATIONS/CONFERANCES, HD(16:9) screens are godsent, as you dont have to fiddle with 'layouts and stuff' and OUTPUT(s) are really WAT U SEE IS WAT U GET !! EASY PEEZZYY!!
d) Since I hardly ever really 'touch type' (Using DRAGON SPEAKS to do this..)and dont really worry about 'screen layouts for any of the MS Apps...however , its FANTASTIC to watch and play BlueRay movies on my W5's&700ds - as I have them with BD writer/players. You really dont see the 16:9 'value' until you play some of the movies on these screens (but then am not easily impressed !)
e) ONE cannot go past numerious websites where one seens the WEBPAGE LAYOUTS has already been changed TO CATER for these 16:9 'displays' ,,,,, thus making it easier to read those pages without "word wrap' etc . In short, its smart busines to cater for these screens<<PLS dont ask me for the URLS of ...>
f)
(for me) its about TIME LENOVO, kinda nice to see a company, in past that has been SLoooowwwww in catering for some of the NEW TRENDS ,,, I think LENOVO ought to be congrulated on getting a nice start on 16:9 screen - yip they still not the LEADERS in that FIRST to the MARKET with most stuff but its nice to see they are DOING IT !! <congrats again>
Hope these above helps ,,,,, and YIP YOU CANT PLEASE em ALL !!
(sorry for typos - am lazy cant be botherd to check)
Cheers!
