Just to play Devil's advocate... but it's my honest opinion....
I was at V last year (Weston Park, Staffordshire). I generally don't like V as a festival, it's a little sanitised and there's not much spirit BUT I have to say it was actually semi-enjoyable last year. The Pixies, Charlatans, Chikinki, BRMC, Kasabian, Kings of Leon, Faithless, Massive Attack etc all made for a couple of decent days.
The Pixies were awesome, a great festival band, what a riot... AND frankly I found The Strokes very disappointing after them.
I had previously seen The Strokes play in London and in Cardiff and on both occasions I thought they were a good live act, much better than they were at V - particularly in December 2003 in Cardiff, that was a great show.
I think the V line-up is actually much better this year.
There are some great LIVE bands; The Hives are brilliant fun to see live, The Departure are excellent and The Prodigy are just amazing. Doves = great, I Am Kloot = nice work and Goldie Lookin Chain will make you cry laughing. Oasis, no matter how dire the new material is, will not disappoint live, as soon as you hear the opening of Live Forever or Cigarettes & Alcohol you will remember why you loved them oh-so-much all those years ago - tears may be shed.
