If you are looking forward to plugging some eSATA products into your laptop, there were until recently very few choices, and today Buffalo came out with a very interesting product: the IFC-EC2SU2, which is in fact an ExpressCard 34/54 with one USB 2.0 port, and an eSATA one (300MB/s Max)… Pretty handy indeed, but unfortunately this product only comes with XP and Vista drivers
