I ditched gmail+calendar a good while back for mobileme, but to be honest I have never been happy with the service. I use Linux at work so require the web interface to these apps during the day. Mobileme's mail webapp is very slow plus the lack of proper filters and smartfolders leave it difficult to use. The calendar webapp doesn't show subscribed calendars so it is basically useless. I'm waiting on a new hardisk to arrive this week so I can clone my mbp before I do a fresh install of lion. I'm seriously considering ditching mobileme mail and calendar and returning to google. I never had a problem with their services and only changed to have the nice integration with all my devices. However if the webapps have improved to provide better filtering, rules, subscription calandars then I would hang on. Anyone tested the beta webapps and seen these possibilities?
