Well, I couldn't resist not piling all my programs on it and it seems to still be performing nicely and still faster than with XP, although I did remove everything from the startup except a few things that were needed. The things I kept in the startup were Capslocknotify, Autohotkey, Wireless disable/enable, Phonerlite and Microsoft Security Essentials.
For some reason though my battery got murdered. My battery used to last a little over an hour but now it lasts about 30 minutes, if that long, and now gives me a message to replace my battery, so something in Windows 7 is tanking my battery. I tried uninstalling/re installing the ACPI management in Device Manager but that did not work, so I am pretty sure there is nothing wrong with my battery.
Now I didn't upgrade the memory so I'm still running around with 1GB stock RAM so I won't be doing much multi-tasking, but then again this netbook sucked at multi-tasking anyway even under XP; they were never designed to handle a heavy load.
Other than the battery, the Dell Mini 10v works perfect with Windows 7 32-bit so if you've been holding off on it, go for it.
