I'll be present, scouting for freebie t-shirts and competition entry forms. This year I'll be taking my PowerBook along, just so I can connect to the wireless hotspots. I may even post photos live from the event (if you're lucky).
They'll be some great bargains to be snapped up. Last year I bought Jaguar for my brother, minus the VAT.
Here's a word of advice. If any stalls are raffling prizes, enter them for a sure win. Most people forget to go back to the stall when they draw the entries. Last year there was about a dozen of us at the MacAlly raffle draw. They drew entries until they found a winner for each prize. Everyone went home happy! I won an AirStick. See you there!
