Hi i'm new to this forum. Just found out about readyboost today and have been researching it a bit today but wanted to find out more before I went in on it...

I'm running Windows07 on a new laptop with 4GB internal memory. I wanted to see if it was worth my while purchasing a SDHC flash card for a little more speed. I was really interested after hearing about it but don't know many people who do this.

Some more direct questions I had were...
-Does any type of flash card work, or does it need to be an SD card?
-I've seen complaints from some that only 4GB can be used, and sometimes less, but the individual who enlightened me told me to purchase an 8GB flash drive for the best product, is this true?
-If i leave the flashcard in almost always but have to eject it from time to time, will this effect anything, and will I have to set it up for readyboost everytime I insert it?
