Acer tablet owners across the country were elated (well, most of them were, anyway) when Acer announced that Ice Cream Sandwich will be coming to the A100 and A500 in April. Thanks to a new leak that made its way to XDA, though, the wait for April just got a lot shorter. Ice Cream Sandwich ROMs for both devices landed in their respective forum on XDA earlier today, bringing a taste of Android 4.0 to the duo.
While early reports have been pretty positive, it appears that these aren't quite final builds just yet. Most noticeably, the "Acer Ring," which is supposed to appear in the official OTA builds, is absent from these leaks. Still, they both appear to provide a fluid stock experience, so if you've been aching to see what ICS is all about on your A500 or A100, hit the links below to download.
Download the file from the source link
Rename it to 'update.zip' (no quotes) and place it on your external SD card

Requires RA Recovery if you want to keep root.

If you're not rooted, download the "original version" from the source link and follow the above instructions for the A100.
As always, if you have any questions, hit up the appropriate thread on XDA.
