now i 'm thinking of either getting this
Acer Travelmate 4025 RM4488
or
the Hp COmpaq v2000 RM4399

i don't recommand anyone to buy local made a notebook. better go for dell, if $$ is a constraint
i have a few question, some expert pls help me:
1) celeron M and Pentium  M also consider as centrino?<= NO, only Pentium M with 1MB L2 cache is considered as centrino processor
2) celeron M and Pentium M power consumption is big different? or same? <=Centrino processors consumes less power
3) can i buy from dell but don wan the original OS? <= IMPOSSIBLE!!
4) possible for 3.5k nb to use for 3dmax autocad?(although slow but still can accept right? <= With that price range, even a notebook with IEG2 can run autocad, rational rose (I supposed you are an engine student?)
5) pls recomeded a around 3.5k nb with
-posible-->centrino? pentium M? <= i recommand you to get Dell Inspiron
-long lasting batteries(at least 4hour)
-can use 3d max and autocad
-some gaming(not necesary)
-don too heavy
-must have wireless
-bigger harddisk is better
-screen size is better 14+ since working on 3D
-usb x 3 or more is better

I think the only option you have now is Dell 510m or I6000, with all the features you required in should be around RM3800, but only the GPU won't cut it for you as it only spot a X300.

As for Acer, there are only two option TravelMate 4151LCi and 4151NLCi, RM3900++ and RM3600++ respectively with on the different in harddisk capacity. But both also don't have the bluetooth and suport only wifi b and only with adequate GPU Intel Extreme 2 Graphics Technology and up to 64MB VRAM.
