I recently bought an ACER Aspire 5740G to replace a five year old Dell Inspiron, which mainly had to go because of a very tired keyboard, but never had any overheating problems. (probably the ambient temperatures are lower here). I still have to get used to the left centered mouse pad of the ACER, but I really need a laptop for both home and travelling.
