The CPU is "really" fast, but: 1 GB RAM in conjunction with the configuration after the installation procedure: That's a No!
Installed 2 GB RAM is impossible, there are the RAM chips "onboard" (= soldered) - I have unfortunately only detected after opening, bottom plate from expanding and keyboard.
There appears to be a "deal" Manufacturer / Microsoft that Windows 7 Starter Memory extended can not be easy. Reason: You do not want to "cannibalize" sales of large notebooks / PC!
That the Starter version of Windows 7 is "only", I like that: Decreased burden by about 300 MB RAM.
Lots of utilities "vermüllen" the system (a fundamental evil. Not only at Asus!). The Lore-master can uninstall it or disable the msconfig startup version, which frees RAM. Or by TuneUp clean (use First 2 weeks for free)
I now have "mucked" total of 6 hours, programs and services. OK, which made some free RAM, but 2 GB RAM I miss.
Internet Explorer 9: I've turned off - that Microsoft has pretty much hidden.
Surfing with Opera 11.6. together with Ad Block now goes smoothly even with several tabs.
Duration is indicated with 5 hours, it looks like that there are at least 4. Here is one, everything disable unnecessary, eg WLAN with shortcut key "Fn 2".
