Question about new touchscreen all-in-one PC's

Hi! I am a new member, and I hope some of the very knowledgeable people on this site can help me. I have been doing research on touchscreen PC's. The two most prominent are the Sony Vaio L series and the HP Touchsmart series. On going back and forth on the specs for both, I am torn. The 24" Sony VPCL114FX/B is available now($1,499), but does not have an HDMI input, has only 512 mb on the graphics card, has a Core 2 Duo E7500 processor and 4 GB of memory. The VPCL 116FX/B is backordered everywhere ($1,799) but has a Core 2 Quad Q8400S processor, 6 gigs of memory and 1 gig of graphics memory. Now I hear that HP has a brand new 23" 600 Quad Touchscreen with a core i7 processor (available in 1.6 or 1.73 Ghz), but it is expensive - $1,869,00 +tax for the 1.6 Ghz if I want the blu ray player and tv tuner, which I do.

Help! Too much input!! My question is, should I seriously look at the HP 600 Quad, go ahead and get the cheaper Vaio 114FX/B, or make myself wait on the backordered 116 FX/B, which my intuition tells me I should do.

Thanks in advance for anyone who can give me so intelligent advice on the above!
