Been playing with the Win7 RC for quite a while now and from what I have seen Win7 runs some older devices much better then XP does now.
Motion Computer M1300 Tablet
Intel Pentium M 1 Ghz
Bus Speed 400 Mhz
Chipset Intel 855GM
1 Gig L2 1.0 Meg Cache
Installed 7 RC and there was an obvious difference in OS response and boot up time.
Dell C840
1.8-GHz P4-M, 1 Gig DDR SDRAM, 37GB hard drive
Even happier! Win7 makes this older laptop run really, really well!
Both of these systems were shipped with and were still running XP and there was no way Vista could run on them. We tried to install it but it was so slow it was useless.
In the past these types of systems were the first to be installed with a distro of Linux to prolong life, but now it seems that Win7 will bring new life to my old hardware.
Do you think you will try to utilize Win7 to breath new life in to your old hardware?
