You might want to check out SplashTop ($4.99, I think).About logmein, I would buy it if it weren't so expensive.
Another vote for LogMeIn. Was hesitant to drop $30, but well worth it.
Same.
Took me a long while to pull the trigger, and now I hate myself for wasting all that time. It is excellent!
For people who don't want to splash out on logmein, if your just looking for a basic remote access app then teamviewer is great. And free!
