dear friends.. Hello I am darshan (my real name) from Bharat (India), NEC, Japan introduced fuel cell powered laptop, I only read about this somewhere.. but I dont know more about it.. but NEC is a very big and popular company.. they claims that our laptop can run 6 hours on each cartridge of fuel cell. so if any1 is a frequent traveller and have no time / place to charge his/her laptop then fuel cell powered laptop is best for him/her.BUT the total cost of fuel cell cartridges per 1 yr useage is = battery replacement expense after 1 yr then it is ok.. and when u charge / use battery powered laptop it will generate heat. But it may not be possible in fuel cell powered laptop.. I also seen 100$ laptop for children, when the battery of this laptop discharged then u can charge it by cranking.But as per my knowledge and belief Desktop has enough room for air circulation then laptop. So desktop will be more long lasting then laptop. But if u take enough care, like always lay laptop on bamboo table which has big enough air wents instead of lap and always try to cool laptop by pedastal / celing fan / air-condition and always protect it from dust and moisture then its life may increase. I have a compaq presario M2305NR 1.6 GHz laptop and when u lay it on yr lap then air wents are blocked. So it is not advisable to use laptop on yr lap for a long time in air went blocked situation. So always lay yr laptop on the table which has a air wents. Or always lay yr laptop on the big thick hard books and be careful that every air wents are open for better air-circulation. additionally, I marked that when u will use any DOS Based application like foxpro / word star etc. on yr laptop / desktop which has AMD cpu then as per AMD supplied hardware monitor, CPU and battery usage will be 100% and temperature of CPU will be increased by 5 degree centigrade. So be carefull.But if u will use any window based application like Visual Foxpro etc. then CPU / Battery usage etc. r very normal.. and faster then any Intel cpu. Regards.. Darshan.
