I have the same problem, my iPad is much slower than before in all aspects. Another thing i do not like is how Safari is now. The former version with the screens is much nicer, now it looks like Explorer.
Absolutely the same here!
My iPad 1 has become sooooo slow after iOS5 upgrade, I get no pleasure using my iPad anymore((
Apple please release somy upgrade to fix it, as it's not bearable now at all.
