Hey, this seems as good as any a place as any to bring up SD card speed; seems quite pertinent to the speed of apps running off the external memory...
I've fully accepted that I'm not going to have a cutting-edge phone until the contract's up on my Eris, and I'm fine with that--I love this phone. However, I'm thinking of ways to eke out as much performance as I can. (I'm eyeing that Seido 1750 mAH battery, for instance, though I'd like to hear how well it works before plunking down $50 for it).
Anyway, I'm also eyeing higher-class SD cards. I'd love to buy a class 6, 16gb card, but I've never had any experience with differently-class micro SD cards: the one that shipped with my Eris is Class 2, which I understand is the slowest--according to Wikipedia, maxes out at 2 Mbytes/second write speed. Class 6 (surprisingly enough) maxes out at 6 Mbytes/second. Each class has correspondingly higher read speeds as well, obviously.
Has anybody tried a higher class SD card in their phone? Did it make a noticeable difference? Is it worth the (relatively hefty) price increase? Does the Eris have the capability to take advantage of the higher read/write speeds?
Again, it's not such a huge issue now (though it'd be nice to decrease some of the hesitation when the phone accesses photos and music), but if apps start running off the SD card, it seems the cards' speed might come into play.
