First a compliment to Amazon, ordered yesterday at noon with standard shipping, this morning already. Many Thanks! Installation was simple and straightforward! Previously 1GB memory were only installed what my my opinion is simply not enough! RAM was immediately recognized and the netbook is now noticeably faster! Especially one notices it at startup and when multitasking, as well as in Office applications such as Excel, Word and especially the Outlook! Price performance / ratio for this Kingston memory is also good! For an equivalent memory of Samsung you have to lie down loose twice! From my mind to know without!
