MBA is about 2 years old, so its due for a major revamp. SSD only, mounted directly to motherboard (save space, thinner, lighter) 3GB (4gb?) of RAM, also mounted SD slot (trend with MB/P's) Dual eSATA/USB socket (USB sucks for large backups and transfers, eSATA for that. Prefer FW800, but will take eSATA) Possibly 2ed USB Expect the MiniDP and audio out to stay, upgraded camera. Likely better screen. Case design will change, of course, but I will leave that imagination to you.
