Which Laptop? Lenovo Thinkpad SL510 or LenovoZ560?

Which computer?

Both are from Costco. I like their return policy and 2 year warranty. Plus if I use American Express card, I will get an additional year of coverage. I have an older IBM Thinkpad 2002, and have been very happy with it. Just time to update.
Also next week Costco has the Acer Aspire 5253-BZ661 ON SALE FOR $399. Pentium Dual core processor, 4GB, 500GB.
Any thoughts on these, THANKS!
