Almost every Android phone features a memory card slot - usually in the MicroSD format. A memory card is useful for all sorts of things - storing pictures and music, as well as e-books. On a rooted phone, you can even store your applications on the SD-card.
There are two main parameters to every micro-SD card:
1) It's size
2) It's speed
For both of these, the general rule is, the bigger the better. Of course, price always rises exponentially when you get to the largest and fastest cards, therefore it makes sense to invest somewhere "in-between".
Some top pics are the Kingston 4GB card, Class 4, which can be bought
here
. The card is class 4, which means it is plenty fast for most users, like those wanting to store pictures. However, for those running apps2sd, you may want to consider a Class 6 card, like the
Transcend 8 GB microSDHC Class 6 Flash Memory Card, which is not only larger, but faster too.
Now, I'm sure that among you, there will be users that want the absolute best. Coming in at a whopping $93.63, the
Kingston 16 GB Class 10 will fill your every need. My opinion: wait it out, these class 10 cards are bound to go down in price soon. Or, if you're fine with 4GB, get

Sandisk is another popular brand, you can get their

,
8GB
,
4GB
or even
2GB
(should you be so inclined) cards.
Nowadays, most computers come with integrated card readers - which should make your life easier, as access to data on the card is often quicker this way. If you have an older PC, you may want to consider investing in a
multi card reader

To summarize , I would suggest you buy at least a Class 4 card with a total capacity of not less than 4GB. Usually, 2GB Class 2 cards come with phones (HTC, SE), so this is a nice step up, without breaking the bank. If your phone is rooted and you are using apps2sd, definitely go for at least a 4GB class 6 card.
