If you want more information than you can handle on the Acer Aspire 1710 series, you should check out the following thread:http://notebookforums.com/showthread.php?t=19756
It has plenty of uniques including a desktop 3.5" HDD that can be upgraded, desktop sized RAM, desktop Northwood and Prescott CPU support, a desktop 17" SXGA LCD display (450:1 contrast ratio, 16ms response time, 4 tube lighting system), etc.
It has a single removable base panel that allows for easy upgrades and replacements to nearly every component including the video card (only if Acer releases a future AGP video card for this line).
It is probably the largest notebook ever built and a big chunk of its 16lb. weight comes from the hard disk and display (you will notice that the display is twice as thick as a normal notebook). If you want a slimmer notebook, the Ferrari 3200 is obviously an excellent choice as others have pointed out.
In any case, just browse that thread and probably any question you might have will be answered.
