For everyone saying it is crappy upgrade/it sucks, etc, it is a very good upgrade. Ill tell you why 1. Faster Processors. Even the slowest CPU, is fairly decent, and is A HUGE bit faster than a netbooks atoms cpu. The newer 2.13 CPU, the SL9600, is probably 30% faster than the older 2.13 P7450. SL9600 has 6MB of L2 cache, while the P7450 has 3MB of L2. More cache =s better performance in pretty much every single application/real world test. 11.6in MBA The 1.4GHz CPU is the SU9400, i believe. It has 3MB of L2 cache and has a 800Mhz bus, which doesnt make sense because the ram is rated at 1066mhz. This thing will be slow, much slower than the others. (still faster than an atom cpu).try to upgrade this CPU, will make a difference. The 1.6GHz cpu (11.6in Upgrade) is the SU9600, it also has 3MB of L2 Cache. I would say its almost as fast older 1.8ghz cpu. If your looking to keep the netbook size, but increase performance a bit then upgrade to the 1.6GHz CPU. And for an extra 100$ is a no brainer. 13.3in MBA Standard 1.86 is the SL9400. Will be a lot of difference between the 1.6 and 1.86. 2.13 is the Sl9600. Again, not a huge difference between 1.86 and 2.13, but it adds up. You should upgrade it tho because its only 100$ 2. Ram I dont know why but there are people complaining/asking on why it only has 2gb of ram. Well just want you to know its upgradeable to 4Gb, which i think is PLENTY for its uses. Its only 100$ so also you should upgrade. You cannot upgrade later because the ram is soldered onto the board, so best to get 4gb to future proof. 3. Hard-drive. The newer Flash hard-drives are indeed faster than the old mechanical drives, but do not get it mixed with SSDs thinking that they are the same. They aren't. SSDs are still MUCH faster than flash memory, but are also much more expensive per GB. Apple went this way to save money and because SSDs wouldn't fit in the current form factor. Its still a decent upgrade. Flash also uses considerably less wattage, =s better battery. 4. GPU The 320M is almost 2x faster than the 9400m. main point is the increase of CUDA cores from 16 to 24, and also a higher core/shader and memory clock speed. It is a 14 TDP gpu, from 12TDP(9400M) So for an extra 2 watts you get some decent performance enhancements. 5. Price point, I dont know about you guys but the REV c was originally 1799 and 1499$ accordingly. ( correct me if i am wrong). They have slashed the prices quite a bit so if someone is complaining that they suck, well then they need some help. With Nice upgrades and cheaper cost i believe now is a good time to upgrade. What do you guys think about the new MBAs?
