The Lexar Micro SD card with adapter is a wonderful invention. It allows you to store vast amounts of information. Both on your PC/Laptop, and/or your mobile phone.
I have a 4.2 GB Micro SD card in my phone. Rather than having to sync my phone with my laptop, I just pop the card out, slide it into the adapter, then plug it right into my SD card slot in my laptop. A few extra steps than just plugging my phone into my computer, but this way, there is no chance of any data going missing.
You know what I mean, right? You start to sync your phone, then your computer crashes, or freezes, and you have to start the whole process over again. With the Lexar Micro SD card, I completely eliminate that risk.
As I said, this is a 4.2 GB card. So, I can store virtually anything on it. Personally, I basically use it to store photo's I take with my phone, and MP3's for some easy listening. Rather than carrying around an extra device, (IE, iPod, etc...).
I picked this Micro SD card up at WalMart, for a pretty good price. It came in a two pack, so, now I have an extra Micro SD card for just backup storage, which is great for someone like me, who's constantly changing, and upgrading my computers, and other electronic hardware.
I give this a 10 out of 10, and highly recommend it for anyone who has a cell phone that supports this feature, or, anyone who just wants to be able to carry their backup data in the wallet.
