Win 7 on Netbooks
Installed Win 7 RS on my Acer Aspire One 150 (120GB HD version), which I've been using Ubuntu Netbook remix on since buying the thing, and have to say I was pleasantly surprised. Set it up as a dual boot, so could compare the two OS's on the same system.
It boots up fast, even cold boots and hibernation, it uses the Aero interface, so looks nice. The interface is responsive, applications load quickly (just as quick as Ubuntu!). The only hardware issue I had was it didn't install drivers correctly for the two card readers (SD on one side, 8 in 1 on the other), but a quick google got me the Vista drivers which installed without complaint and didn't even need a reboot.
Only real issue is memory usage, mine is a 1GB model, and after boot up I have about 480MB free, but that's still plenty to have Firefox, Openoffice and several other tasks open at the same time before running into VM usage. Plus the left hand SD card slot is a flush mounted slot, so designed to supplement your internal storage with an SD cardthat you just plug ain and leave there (mainly for 8GB SSD models), so I just stuck a spare 512MB SD card in there and swiched on ready-boost, which helps speed up VM by quite a factor.
Have to say if you switch on Auto-hide for the task bar, Win 7 also makes much better use of the limited available screen space than Ubuntu NBR does.
I also love the new (in Vista and above) combined search/run bar in the Start menu. No more having to search for that elusive application icon, because you can't find the right start menu, because you've forgotten the publishers name etc. Just type the first few characters of the application name and it just appears in the list above! It's almost like M$ have realised that a GUI full of icons isn't always the easiest way of managing applications! (I wish Ubuntu had this!)
Installed Steam and Half-Life, just for fun to see if it was playable, and it was! Even in 800x600, although 640x480 gave better frame-rates, but definitely usable. Obviously it's only a Netbook, so not really a game machine, but still interesting to see :-)
Still a little unstable, had a couple of blue-screens, usually while Windows was trying to run updates. But it is only an RC and has been updated since for the RTM. Plus some of the hardware drivers still may not be fully correct for Win 7, but those will get fixed in time, especially if Acer start releasing Win 7 versions of their Netw
Hate to say this, as I'm not really an M$ fan, despite what I say above, but Win 7 is nice, both to look at and use, much better than Vista (but then what isn't!).
If the stability issues can be resolved, I can see me moving from Ubuntu to Win 7 on my Netbook, unless the Ubuntu crowd do some improvements the the user experience and drag the look and feel of Ubuntu out of the early 90's!
