i'm currently trying out both programs for the next 25 days. i really like them both but i need feed back on which ones to purchase.
vmware- Guest OS: SuSE 8:
Likes:
- it hasn't crash yet in 36hrs of use. even with my system
OC'ed from 2.26 to 2.9 when installing SuSe 8.
- i like the fact that you can add more than one virtual disk and add all your cd devices. for me the cd-rom, cd-rw, and dvd-rom.
- i like the vmware tools included with linux. i can switch my guest OS to 1200x1024 and i don't have to worry about releasing the mouse from the guest to the host.
- i can install 2 virtual usb devises like my mobile action IR device and usb digital cam
- SuSE 8 is very fast as a guest OS. almost as fast as installing it in it's own drive.
- my USB mouse and wheel works!
Dislikes:
- i can't copy files directly from the host to the guest without using the virtual network.
- still can't get the sound card to work. i reckon that's just a n00b problem.

- could not get redhat 8, mandrake 9 to work. i think it's a video driver problem. another n00b problem.
virtual PC- Guest: Mandrake 9, redhat 8, suse 8, BE|OS
Likes:
- i can get all the distros to work, even BEOS, unlike vmware.
- i like the "undo drive" feature
Dislike: i haven't thoroughly test VPC but these are just some likes and more dislike...
- RH8, mandrake 9 took too much time to install. even on two different host system (P4 and AMD)
- RH8 running too slow.
- i couldn't change the resolution to more than 1024x768.
- the sound (emulated SB16) still dudn't work.
- can't install more than 1 cdrom
- can't get my usb devices to work properly.
