I have the Microsoft Surface Pro 128. The Pro 2 is out with 256 SSD drive and 8 gigs memory. It Handles photoshop and lightroom without issues and has USB 3.0 for external storage (I use for backup) and SD card slot (for double backup when travelling).
Also has a pen which comes in handy for editing. Very lightweight and fast.
Stayed at Ocean Vida in Malapascua. Nice place. Connected to Sea Explorers dive operation. We had a small group and 7 and were very well taken care of. Diving is all from boats and you usually plan the dives the day/night before.
