I was always a PC gamer (well, technically I have started off with a Chinese bootleg NES, but that hardly counts as I couldn't understand the games at all and the only reason I could finish a bunch of them was because of sheer determination and the immense amount of free time only childhood can account for). I got my first tabletop when I was fourteen, which was a laughable 2Ghz Celeron, 256Mb RAM, 32Mb VRAM office machine that I somehow still managed to whip into use. After a few upgrades it actually managed to run most games, and I actually became such an optimization-hound that even managed to run Half Life 2 with a decent frame rate even though all my specs were waaaay below the minimum requirements.
Then I got myself a decent laptop when I got 18, and I never looked back since then, using up two other laptops in the meantime. Nowadays I cannot even imagine myself using a tabletop, as in my opinion a good laptop can fulfill all the roles your PC already can, and then some, while eating less electricity and taking up less space. The current machine I use is an AMD Turion II 2.3Ghz machine with 3Gb ram and a 1Gb AMD Radeon 5450, which wasn't a great machine even in 2011 when I got it, yet it still serves me pretty damn well, I can run most modern games after slight tweaking and, most importantly, I can play Skyrim and Fallout NV, the only two games I keep returning to, on high setting without a problem. Really, the only reason why I would ever switch over to a console would be if the manufacturer would pay for
me. On the other hand, show me a console that is portable, lets you play games, watch movies, anime, TV series,, browse the internet, read manga and ebooks, play niche stuff like visual novels and browser-mmos' and lets you do a thousand other things as well, and I might just change my mind.
