I don't think that tablets are going to kill all of the elements of the smart classroom, particularly the projector, which is still way to useful. But it will kill many of them. The smartboard is dead. Ded. I use my iPad and my projector along with the Doceri software. My solution was 1/2 price of the smartboard in the classroom next door, and allows me to roam around the room while presenting. I can also create my presentations wherever my iPad is as opposed to needing to be in the room with the smartboard or at a PC with specialized software.

Instead of clickers I simply have all of the students twitter answers to me. Since it is not graded, it is ok if some student forgot to charge their phone on a particular day. I do have a couple of iPod Touches for use by students who don't have a phone that can tweet.

If you don't get one month (4 weeks) a year off get a new job. Standard salaried leave is at least 2 weeks vacation and 10 holidays. I personally get 12 holidays and 3.5 weeks a year though that includes my sick time. I'm considered entry level at my company at well. I can also work from home depending on my assignment. Teachers get 2 months off sure, but they aren't exactly at the Teacher's discretion. One of my friends is a teacher, she gets 24 hours of discretionary leave a year. That includes things like doctors appointments, A/C repair guy visits so on and so forth. I've never seen it actually used for vacation. It makes taking a trip anytime but the summer quite hard.
