Hybrid/Convertible Computer

I'm looking at one of these new hybrid/convertible computers. Currently, I don't have a laptop as my phone normally suffices for my day to day when I'm out of town and ipad doesn't offer ability to work in excel. With these new Windows 8 systems, I am thinking about the grabbing one. I particularly like the hybrids. The HP Envy x2 has caught my eye.

What I need is a laptop I can use for simple spreadsheet, Ms word, powerpoint, email and web browsing and I need a tablet for presentations. I think the envy x2 works perfectly for those. The third way I want to use it is to hook it to the TV in my conference room (50") and operate google earth, Microsoft office, web browsing, adobe or pictures. Does a computer like that have the ability to push to a 50" tv without jumping around and looking like hell? If it doesn't, what do I need that will work to that effect?

Thought about that and may still do it. I just like having the functionality of both a tablet and a laptop if possible.

Asus makes a pretty neat device called the Transformer. You could buy two of them for less than a Macbook Air. Not sure if it will be suitable, but it's a very nice and solid device. They're also about to roll out a device called the padphone. Your smartphone will dock into the tablet.

Windows 8 hasn't been around long enough for me to invest in their tablets. I'll let someone else be the guinea pig.

Ultra portable typically translates to ultra slow. My laptop weights 8 lbs and the battery lasts 2 hours, but I love it. I've had it for 3 years and its still fast.

My biggest concern with the HP is that is runs intel atom and not an i5. If it weren't for that, I would be in. Can't decide but I think I definitely want one of the ones where the screen pulls off into a pad.

Then there is the Ultrabook. Lots of nice models, but they're pricey.

but they don't turn into a "pad" very well and the ones that do, like the xps, are real expensive and you still have the weight of the whole computer.

Hps are good when loaded graphically yet I find not very durable. I've broken 2 within 6 months after purchasing but I am unintentionally brutal on cell phones and laptops etc. Dells are more basic but durable. Macs are as well but expensive.
