Should i get a 40 inch tv or no?

My parents just got divorced, long story short, my dads the poor one and my moms the rich one, at her house is a bunch of hd tvs with every channel, and me and my dad have nothing, so a bunch of his friends gave us there old tube tvs. Ill admit i miss my hdtv for my xbox, i found an hdtv at hhgregg for 289.99$ and for my birthday i get like combined total of 400$ from all family, but $150 is going to something else, and i like having money so my dad also agreed to pay $100 of it, but its half of my christmas present, and ill have like 80$ left, but when i told him he was like, all that work we did driving around to get those, and getting it in your room… And i felt bad about that so i don't know if i still want it, well i want it but you know what i mean, we don't even have hd tv channels but i just want it for my xbox cause i love hd tv for xbox. If i don't buy it i was thinking of getting a few games back that i want, like ssx and left for dead, maybe other stuff and i don't know what to buy other than what i said. I don't skate, i have plenty of clothes, i'm a guy, i have an xbox, 2 ipod touchs, (ones my sisters that she gave me, the other was my christmas present in 6th grade) 2 Iphone (ones mine ones my dads old one) and an ipad (i saved up for 2 years by mowing lawns to get it, and beats by dre (also mowing lawns).So i have basically all the electronics i want, so that's not an idea, except the new itouch is tempting($300! Though). I don't know what it is but i haven't watched or played on a tube tv for like 4 years so its very weird. Plus my dad said i should maybe start saving for car stuff

If I were you I would still get the HDTV, but I would put it in the living room so you and your dad can enjoy it together. Not only do you get an HDTV for your Xbox but, it may lift your dads spirits that you and him get to spend some quality time together.
