Once you go notebook you never go back! Bah, you'll be back. 😀
Funny thing is I've been at the dawn of both, I've owned (well alot of it parents for early stuff, but I was primary user);
Desktop: Commadore PET, Apple ][, Vic-20, IBM PC twin floppy + CGA, COCO, TimexSinclair, C-64, PCjr, Mac, PS/2Model 25 - 286, PS2 Model30 -386, PS/2 Model 50-486, IBM 300GL, Then build your owns.
Noteboook/portable: IBM 5155 twin floppy, IBM convertible (still to this day my favourite 'whoa' factor PC), PS/2 Model 30 Note (386), Thinkpad 700C (486SL), Thinkpad 380ED (P166MMX w/ 2MB NeoMagic), ThinkPad 390X (PII-366 w/ 7MB Neomagic), then the Dell 5150, and now the Gateway NX850Z. Next who knows.
Plus I've used a TONs of gear my dad brought back as product planner for IBM including a PowerPC (IBM, not Apple) desktop and Laptop (never really made it to market), compaqs a few more Apple products like the LISA.
Funny for an IBM guy his last 4 computers have been iMac G3 Tangerine with DVD, iBook (plain white 12"), G4 iMac/DeskLamp 17", and G4 PowerBook 12". 8O
I thought about this, but I have'nt been able to get a straight answer from Alienware or Dell about upgrading GPU on a notebook , if I could upgrade at least 1 time per/lifespan of notebook I would consider going portable.
Depends on the model, thetop models of Alienware and Dell ARE upgradeable, but I know those two use proprietary interfaces, thus you need to buy from them, and therefore might as well have them install it (free with purchase). I know Voodoo does offer upgrades too, but I think their are straight unchanged Axiom and MXM solutions, so easier upgrade path (if you can find the proper parts yourself).
For me upgradability seemed like a great idea, but like I mentioned,probably cost so much, might as well sell the whole laptop and then take that money and get all new gear plus warranty. Like right now, instead of addin a 2GHZ PM and X800 to my rig, I'd prefer a DUO core (or better) plus X1K or GF7 series part with the support for DDR2-667 and slightly larger HD (mine's 100GB new standard for this specific laptop 120GB), plus better LCD, new standard is WSXGA instead of WXGA for this laptop. Right now the sweet thing is the NX860 uses the same battery (I have 2) so I could keep my extra one. I just hope gateway keeps the same connector one when they upgrade to the merom version, or else they lose oneof their biggest benifits to me right now. 2 batteries let's me actually game on flights 2+ hours of HL2/FartCry , 3-4+ hourse of Morrowind using both batteries. Haven't played Oblivion yet, but probably similar to HL2/FartCry.
