    I'm considering buying a T60 widescreen with vista. I noticed that physically the machine can hole 4GB of ram but it will only recognize 3GB. Anyone else bothered by this?

    I know 4GB of ram is extremely expensive right now but it'd be nice to know that the option to do it is there when the price falls.

    "By default, Version 5 processes on Windows can allocate up to 2.0GB of memory for storing data and code. The 4GB address space offered by the operating system is split in two areas of 2GB each: the first 2GB is for user mode, and the other 2GB isg reserved by the kernel. On Windows® XP®, it is possible to increase the default allocation capabilities up to 3.0GB (3GB for user mode, 1GB reserved for kernel). Such capability requires additional tunings in order to be effective"

    So look like there is a switch to let 3 GB of user space memory, but you can't do better than that in XP pro 32 bit. 2 GB is the default. Though Lenovo could have limited things somehow I doubt they did. Check what the BIOS sees for memory amount. If it see 4 and the OS sees 3 its probably just reporting user space memory.
