#1: Acer Aspire 6930 bought on post-xmas sale from Staples. Core 2 Duo T5800, 4GB DDR2 667, 250GB SATA HD, Integrated Intel 4500MHD, Intel 5100 wireless.
Problems: Sometimes audio driver doesn't automatically detect headphones plugged in and switch speaker output to headphone jack. Oh and HDMI audio may have the same issue if turned on while hooked to a TV that's off.
#2: Piece of Junk (literally) desktop. Core 2 Duo E6300 @ 3.63GHz on Asus P5B, 2GB DDR2 1066, ATI HD4850, 400GB SATA HD.
Problems: None.
#3: Toshiba Portige 4010 (So old it came with Windows 2000 installed because XP wasn't even out yet): Intel Pentium III mobile 933MHz Low Voltage, 512MB RAM, 30GB IDE HD, Intel 2200BG wireless, Ali integrated video and MB chipset from hell.
Problems: Newest Video driver for integrated Trident Blade3D (DX7 class) video is circa 2002. Windows 7 build 7000 automatically detects the install issues and retries with compatibility settings and succeeds . The driver works, except when it tries to create an overlay surface it locks up. This is not a bluescreen, the chipset actually freaks out because it's crap and the driver is badly written. Same issue under XP (which the driver was written for) on this machine. Using the video in SVGA mode solves the crash problem but is too slow for video playback. Fine for browsing and word processing though.
Performance is slow, but usable on a 9 year old laptop. Checking memory usage with the default install of "Ultimate" edition using Win7's Resource Monitor shows it defaults to only using about 300MB of RAM, leaving about 200+ free for apps and cache. This is with all the bloated defaults running like Homegroup services etc. Despite the fact that it's still beta, it fares much better than Vista and I say even on par with XP in terms of running within limited resources, while delivering more features than XP.
So yeah, color me impressed. No it's not going to render Toy Story in realtime on a 386 with EGA while making toast and finding Sarah Conner, but still that's a decade old laptop (which means it's a steaming turd of proprietary crap) and Win7 is still usable on it, without a week of fiddling with settings first. Considering MS is talking about "Netbook versions" of Win7 I'd say there's definitely a chance of them producing a contender for the lower-spec hardware out there that fares much much better than Vista did.
