As others have said, you're not supposed to replace the memory card for WP7 mobiles. I have a LG Optimus and I've never had any slowness issues.
I was concerned about the lack of upgradable memory before the purchase but it's nice to not have to worry about switching in and out cards and worrying about exactly where anything is saved. I did make sure I purchased a 16MB model though, being stuck with 8MB would suck.
