I think a factory reset is the best thing to do after a big upgrade like the jelly bean one.
I had no problem this way with the tablet.
I personally use the Nova Launcher from the first day with the arc and everything is smooth. It uses only 45/50MB of ram (half of tapestry) and icon resolution is higher. More a pleasure to use and see.
I think that kobo developing team made a great job in the ICS firmware for the arc, this is why we see not great improvement with jelly bean update.
Everything seems to run little smoother and better (games also).
I use a sony smartphone and the ics upgrade was a nightmare.
Hope they keep going on working on future upgrades to solve all problems.
The Arc is a very nice tablet, the greatest complain is the lack of gps and bloothoth for app compatibility.
i'm a little worry about some incompatibility issue with apps and games (modern combat 4???) luckly is possible to sideload the apk installer (see flickr and nfl gamepass)
