Tablet laptop?  

Most of my friends and I think that Vaio is overpriced. It is mainly style so if you want to look fashionable, Vaio is the way to go. Since its Sony, it Should last and quality and all should be alright.
Since you said its for school and entertainment purposes, I will recommend HP for its entertainment capabilites, although I won't get the tablet because the only good thing is its cool. But I most probably won't use it and its one more thing that could go wrong. But thats just my opinion.
If you want extreme entertainment capabilities do take a look at MSI and Asus. Some of their laptops are just plain sick, performance-wise but style is a little lacking sometimes.
And if your entertainment purposes include games avoid MacBooks. Its not the compability issues with BootCamp now, but rather, it heats up easily because in BootCamp mode its fans will only spin at 1000rpm and the only ventilation is the small little slit obstructed by the screen.
Happy Laptop shopping and I hope you'll like whichever laptop you choose!
