I come from the world of Blackberry, and I remember Vlingo having about as many (memory) leaks as a sieve. Now that I'm on Android, I'm wondering if there are any inherent problems with Vlingo? Has anyone had a problem with it keeping the phone from sleeping? Or any other mentionable problems? I'm coming up on my 24 hrs with it, and so far it seems solid, but I'm wanting to know if there are things that might not have yet cropped up before I let my $10 go to it. Thanks!
