I've seen this mentioned a few times now, but how significant is it really? I can't really seem to find much about it... I'm using Apps2sd right now and I love how much extra space it gives me. I also don't notice any slowdown when running apps (at least so far). Of course I'll be getting a new phone next year when my NE2 is ready, which of course will come with a new card, so do I even need to worry about this? Any Mythbusters out there?
