I just bought my new HP Mini 1030 from BestBuy two days ago, and It's the most amazing new gadget i've ever bought. I only had the netbook for about 10 minutes before I took it apart and got rid of that gross XP it came with.
I took the 1GB stick of ram out and replaced it with a Kingston KVR2GB 2 gig stick of DDR667 SODIMM DDR2 immediately. I also bought a 2GB PNY 133mb/s SD card to use for readyboost, and I'm also using the 2GB transcend mini HD the netbook came with in the box.
I had to install vista from an external USB DVD-ROM I bought as a spare. The install took less than 30 minutes from bootup to seeing the desktop. One small problem I had was the drivers; THEY WERE IMPOSSIBLE TO FIND! For some reason, the VGA and WLAN drivers didn't install with Vista. With some searching for about 4 hours on Google, I finally found them. The HP Minis use a Broadcom 802.11b/g internal WLAN card and an intel GMA950 graphics card. The intel site says the GMA950 driver is for XP only, but the download page says vista on it. The Broadcom WLAN driver can be used from the MIni 2100 series of netbooks driver pages on the HP site.
After installing vista, I did the following tweaks to shorten startup, make more ram available, and speed up the system. These can all be googled:
-Disable GUI bootup screen
-Enable both cores of the CPU in the vista system msconfig (defauly is 'auto')
-Disable hibernation file
-Disable vista search indexing
-Disable AERO visuals (Even though the system works JUST FINE with AERO!)
The system uses 800MB of the 2048MB at idle, which is fine because the most intensive program I run is firefox. Firefox has a plugin called Firebug Lite which allows firefox to run MUCH faster on flow speed processors with lower cache like the Atom. The CPU never spikes above 6% when opening programs, and barely hits 100% with them open. I'm using my SD 2GB card for readyboost which I'm assuming is helping allot. My 2GB mini HD usb port is being used as spare storage.
Hope this helps people who are wondering...
